# Case-Sensitive Search

Case-sensitive search allows you to search for terms with a particular capitalization. To use case-sensitive search, you must set AdvancedCaseSearch to `True` in the configuration file.

To indicate that you want to match case for a term, prefix it with a tilde (~). For example:

    action=Query&Text=~Lovely

In this example, HPE IDOL Server stems the term `Lovely`, and matches case-sensitively. For example, it matches Love, Lovely, and Loved, but not lovely or LoVeLy.

For more information about case-sensitive searching, refer to IDOL Expert.

You can use also case-sensitive matching in combination with phrase search to match exact terms.

Word Match Example

    action=Query&Text="~Lovely"

HPE IDOL Server does not apply stemming. When it matches the query, HPE IDOL Server returns only documents that contain a word that exactly matches the query word. The query `"~Lovely"` can return only documents that contain the word Lovely.

Phrase Match Example

    action=Query&Text="fresh and ~Lovely"

HPE IDOL Server removes any stop words that the query contains (the example query above contains the stop word and), but it does not apply stemming:

    action=Query&Text="fresh ~Lovely"

When it matches the query, HPE IDOL Server returns only documents that contain a phrase that matches the phrase in the query string. The query `"fresh and ~Lovely"` can return only documents that contain a phrase that matches the phrase fresh Lovely (for example, fresh Lovely, fresh and Lovely, Fresh or Lovely, and so on).
