    For hyphenated strings or special characters, consider [specialized analyzers](index-add-custom-analyzers.md#built-in-analyzers). One example is [keyword](https://lucene.apache.org/core/6_6_1/analyzers-common/org/apache/lucene/analysis/core/KeywordAnalyzer.html) that treats the entire contents of a field as a single token. This behavior is useful for data like zip codes, IDs, and some product names. For more information, see [Partial term search and patterns with special characters](search-query-partial-matching.md).
 
 > [!NOTE]
-> Full text search is conducted over terms that are tokenized during indexing. If your queries fail to return the results you expect, [test for tokenization](/rest/api/searchservice/indexes/analyze) to verify the string you're searchin for actually exists. You can try different analyzers on strings to see how tokens are produced for various analyzers.

 ## Create a skillset
 
 Skills are the basis for integrated data chunking and vectorization. At a minimum, you want a Text Split skill to chunk your content, and an embedding skill that create vector representations of your chunked content.
 
-In this skillset, an extra skill is used to create structured data in the index. The Entity Recognition skill is used to identify locations, which can range from proper names to generic references, such as "ocean" or "mountain". Having structured data gives you more options for creating interesting queries and boosting relevance.
