 ## Query languages
 
-In OpenSearch, you can use the following query languages to search your data:
-
-- [Query domain-specific language (DSL)]({{site.url}}{{site.baseurl}}/query-dsl/index/): The primary OpenSearch query language that supports creating complex, fully customizable queries.
+In OpenSearch, you can use the following query languages to search your data.
 
-- [Query string query language]({{site.url}}{{site.baseurl}}/query-dsl/full-text/query-string/): A scaled-down query language that you can use in a query parameter of a search request or in OpenSearch Dashboards.
+Language | Where you can use it | Description
+:--- | :--- | :---
+[Query domain-specific language (DSL)]({{site.url}}{{site.baseurl}}/query-dsl/index/) | Search API, Dev Tools | The primary OpenSearch query language that supports creating complex, fully customizable queries.
+[Query string query language]({{site.url}}{{site.baseurl}}/query-dsl/full-text/query-string/) | Search API `q` parameter, Discover and Dashboard search bar | A scaled-down query language whose syntax is based on Apache Lucene.
+[SQL]({{site.url}}{{site.baseurl}}/search-plugins/sql/sql/index/) | SQL API, Query Workbench | A traditional query language that bridges the gap between relational database concepts and the flexibility of OpenSearch's document-oriented data storage.
+[Piped Processing Language (PPL)]({{site.url}}{{site.baseurl}}/search-plugins/sql/ppl/index/) | PPL API, Query Workbench | The primary language used with observability in OpenSearch. PPL uses a pipe syntax that chains commands into a query.
 
-- [SQL]({{site.url}}{{site.baseurl}}/search-plugins/sql/sql/index/): A traditional query language that bridges the gap between traditional relational database concepts and the flexibility of OpenSearch’s document-oriented data storage.
+For information about querying data in OpenSearch Dashboards, including the Dashboards Query Language (DQL), see [OpenSearch Dashboards query languages]({{site.url}}{{site.baseurl}}/dashboards/#query-languages).
 
-- [Piped Processing Language (PPL)]({{site.url}}{{site.baseurl}}/search-plugins/sql/ppl/index/): The primary language used with observability in OpenSearch. PPL uses a pipe syntax that chains commands into a query.
+## Customizing search results

-## Search performance
+## Optimizing search quality
 
-OpenSearch offers several ways to improve search performance:
+OpenSearch provides comprehensive tools and features to help you measure, analyze, and improve the quality of your search results. These integrated features work together to optimize search relevance based on user behavior and machine learning. For more information, see [Optimizing search quality]({{site.url}}{{site.baseurl}}/search-plugins/search-relevance/).
 
-- [Asynchronous search]({{site.url}}{{site.baseurl}}/search-plugins/async/): Runs resource-intensive queries asynchronously.
-
-- [Concurrent segment search]({{site.url}}{{site.baseurl}}/search-plugins/concurrent-segment-search/): Searches segments concurrently.
-
-## Search relevance
-
-*Search relevance* is a measure of how well a document matches a search query. When you run a search query, OpenSearch compares the words in your query to the words in each document and assigns a relevance score based on factors such as how frequently the words appear and how closely they match. For more information, see [Relevance]({{site.url}}{{site.baseurl}}/getting-started/intro/#relevance).
-
-To help you fine-tune and improve search relevance, OpenSearch provides several specialized features:
-
-- [Search Relevance Workbench]({{site.url}}{{site.baseurl}}/search-plugins/search-relevance/using-search-relevance-workbench/): A suite of tools that support search quality improvements through experimentation. 
-
-- [Querqy]({{site.url}}{{site.baseurl}}/search-plugins/querqy/): Offers query rewriting capability.
+## Search pipelines
 
-- [User Behavior Insights]({{site.url}}{{site.baseurl}}/search-plugins/ubi/): Links user behavior to user queries to improve search quality.
-  
-## Search results
+Search pipelines are the foundational infrastructure that enables OpenSearch's AI and vector search capabilities. They provide modular processors that can transform queries (text-to-vector conversion, ML inference, query rewriting), enhance results (reranking, RAG, field manipulation), and orchestrate complex AI workflows. For more information, see [Search pipelines]({{site.url}}{{site.baseurl}}/search-plugins/search-pipelines/).
 
-OpenSearch supports the following commonly used operations on search results:
+## Improving search performance
 
-- [Paginate]({{site.url}}{{site.baseurl}}/search-plugins/searching-data/paginate/)
-- [Paginate with Point in Time]({{site.url}}{{site.baseurl}}/search-plugins/point-in-time/)
-- [Sort]({{site.url}}{{site.baseurl}}/search-plugins/searching-data/sort/)

-Search relevance evaluates the accuracy of the search results returned by a query. The higher the relevance, the better the search engine.
+_Search quality_ refers to how well search results match user intent and expectations. OpenSearch provides several features and tools to help you measure, analyze, and improve the quality of your search results.
 
-OpenSearch provides the following search relevance features:
+OpenSearch offers the following features to help you optimize search quality:
 
-- [Search Relevance Workbench]({{site.url}}{{site.baseurl}}/search-plugins/search-relevance/using-search-relevance-workbench/): A suite of tools that support search quality improvements through experimentation.
+- **[User Behavior Insights (UBI)]({{site.url}}{{site.baseurl}}/search-plugins/ubi/)**: Capture and analyze user behavior data to understand how users interact with search results and identify areas for improvement.

+
+- **[Learning to Rank (LTR)]({{site.url}}{{site.baseurl}}/search-plugins/ltr/)**: Use machine learning models trained on behavioral data to improve the ranking of search results.
+
+- **[Reranking search results]({{site.url}}{{site.baseurl}}/search-plugins/search-relevance/reranking-search-results/)**: Apply machine learning models to reorder search results for improved relevance.
+
+## Search quality workflow
+
+A typical search quality improvement workflow involves:
+
+1. **Data collection**: Use UBI to capture user behavior and interaction data.
+2. **Analysis**: Analyze user behavior patterns to identify search quality issues.
+3. **Experimentation**: Use the Search Relevance Workbench to test different approaches.
+4. **Model training**: Train LTR models using behavioral data to improve ranking.
+5. **Query enhancement**: Apply query rewriting rules to improve query understanding.
+6. **Reranking**: Apply ML-based reranking to further optimize results.
+7. **Evaluation**: Continuously monitor and evaluate search performance.

-# Search options
-
-What users expect from search engines has evolved over the years. Just returning relevant results quickly is no longer enough for most users. Now users seek methods that allow them to get even more relevant results, to sort and organize results, and to highlight their queries. OpenSearch includes many search options, described in the following table, that enhance the search experience.
-
-Option | Description
-:--- | :---
-[Autocomplete functionality]({{site.url}}{{site.baseurl}}/opensearch/search/autocomplete/) | Suggest phrases as the user types.
-[Did-you-mean functionality]({{site.url}}{{site.baseurl}}/opensearch/search/did-you-mean/) | Check spelling of phrases as the user types.
-[Paginate results]({{site.url}}{{site.baseurl}}/opensearch/search/paginate/) | Rather than a single, long list, separate search results into pages.
-[Point in Time]({{site.url}}{{site.baseurl}}/search-plugins/searching-data/point-in-time/) | Run different queries against a dataset that is fixed in time. 
-[Sort results]({{site.url}}{{site.baseurl}}/opensearch/search/sort/) | Allow sorting of results by different criteria.
-[Filter results]({{site.url}}{{site.baseurl}}/search-plugins/filter-search/) | Filter search results.
-[Collapse results]({{site.url}}{{site.baseurl}}/search-plugins/collapse-search/) | Collapse search results.
-[Highlight query matches]({{site.url}}{{site.baseurl}}/opensearch/search/highlight/) | Highlight the search term in the results.
-[Retrieve inner hits]({{site.url}}{{site.baseurl}}/search-plugins/searching-data/inner-hits/) | Retrieve underlying hits in nested and parent-join objects.
-[Retrieve specific fields]({{site.url}}{{site.baseurl}}/search-plugins/searching-data/retrieve-specific-fields/) | Retrieve only the specific fields
+# Customizing search results
+
+OpenSearch provides fundamental search capabilities and options that form the foundation of most search applications. These features work with all search types including keyword, vector, and AI search.
+
+## Pagination
+
+Control how search results are accessed across large result sets:
+
+- [Paginate results]({{site.url}}{{site.baseurl}}/search-plugins/searching-data/paginate/): Rather than a single, long list, separate search results into pages.
+- [Point in Time]({{site.url}}{{site.baseurl}}/search-plugins/searching-data/point-in-time/): Run different queries against a dataset that is fixed in time.
+
+## Sort and filter
+
+Apply the most common result refinements:
+
+- [Sort results]({{site.url}}{{site.baseurl}}/search-plugins/searching-data/sort/): Allow sorting of results by different criteria.
+- [Filter results]({{site.url}}{{site.baseurl}}/search-plugins/filter-search/): Filter search results based on specific criteria.
+
+## Result processing
+
+Control what data is returned and how it's organized:
+
+- [Collapse results]({{site.url}}{{site.baseurl}}/search-plugins/collapse-search/): Collapse search results to show only unique values for a specified field.
+- [Retrieve specific fields]({{site.url}}{{site.baseurl}}/search-plugins/searching-data/retrieve-specific-fields/): Retrieve only the specific fields you need.
+- [Retrieve inner hits]({{site.url}}{{site.baseurl}}/search-plugins/searching-data/inner-hits/): Retrieve underlying hits in nested and parent-join objects.
+
+## Result formatting
+
+Customize how search results are visually presented:
+
+- [Highlight query matches]({{site.url}}{{site.baseurl}}/search-plugins/searching-data/highlight/): Highlight the search term in the results.
+
+## Query enhancement
+
+Enhance user queries in real-time to improve search accuracy and user experience:
+
+- [Autocomplete functionality]({{site.url}}{{site.baseurl}}/search-plugins/searching-data/autocomplete/): Suggest phrases as the user types.
+- [Did-you-mean functionality]({{site.url}}{{site.baseurl}}/search-plugins/searching-data/did-you-mean/): Check spelling of phrases as the user types.
