 # Skills for extra processing during indexing (Azure AI Search)

+This article describes the skills in Azure AI Search that you can include in a [skillset](cognitive-search-working-with-skillsets.md) to access external processing. 
 
 A *skill* provides an atomic operation that transforms content in some way. Often, it's an operation that recognizes or extracts text, but it can also be a utility skill that reshapes the enrichments that are already created. Typically, the output is text-based so that it can be used in [full text search](search-lucene-query-architecture.md) or vectors used in [vector search](vector-search-overview.md).
 
 Skills are organized into categories:
 
-* A *built-in skill* wraps API calls to an Azure resource, where the inputs, outputs, and processing steps are well understood. For skills that call an Azure AI resource, the connection is made over the internal network. For skills that call Azure OpenAI, you provide the connection information that the search service uses to connect to the resource. A small quantity of processing is non-billable, but at larger volumes, processing is billable. Built-in skills are based on pretrained models from Microsoft, which means you can't train the model using your own training data.

 * A *custom skill* provides custom code that executes externally to the search service. It's accessed through a URI. Custom code is often made available through an Azure function app. To attach an open-source or third-party vectorization model, use a custom skill.

 # Lucene query syntax in Azure AI Search
 
-When creating queries in Azure AI Search, you can opt for the full [Lucene Query Parser](https://lucene.apache.org/core/6_6_1/queryparser/org/apache/lucene/queryparser/classic/package-summary.html) syntax for specialized query forms: wildcard, fuzzy search, proximity search, regular expressions. Much of the Lucene Query Parser syntax is [implemented intact in Azure AI Search](search-lucene-query-architecture.md), except for *range searches, which are constructed through **`$filter`** expressions.

 To use full Lucene syntax, set the queryType to `full` and pass in a query expression patterned for wildcard, fuzzy search, or one of the other query forms supported by the full syntax. In REST, query expressions are provided in the **`search`** parameter of a [Search Documents (REST API)](/rest/api/searchservice/documents/search-post) request.

 Filtering occurs in tandem with search, qualifying which documents to include in downstream processing for document retrieval and relevance scoring. When paired with a search string, the filter effectively reduces the recall set of the subsequent search operation. When used alone (for example, when the query string is empty where `search=*`), the filter criteria is the sole input.
