# AdvancedSearch

Set `AdvancedSearch` to `True` to use an advanced weighting algorithm that improves conceptual querying.

Enabling `AdvancedSearch` allows you to search for an exact word or phrase match. When you query for a word or phrase that is enclosed in quotation marks, IDOL Server matches it in its exact (unstemmed) form (query text that is not enclosed in quotation marks is still matched conceptually).

`AdvancedSearch` is not affected by enabling or disabling stemming.

NOTE: Enabling `AdvancedSearch` has no notable effect on the IDOL Server index size.

Enabling `AdvancedSearch` does not prevent IDOL Server from discarding stop words at index and at query time.

If you enable `AdvancedSearch`, Micro Focus recommends that you set ProperNames to `7` in the appropriate language type sections of the configuration file.

If you enable `AdvancedSearch`, you can still run a conceptual phrase search that uses stemming by using `DNEAR1`.

Word Match Example

    action=Query&Text="lovely"

IDOL Server matches the exact form of the term.

When it matches the query, IDOL Server returns only documents that contain the exact term that you specify in the query. The query `"lovely"` can return only documents that contain the word lovely.

Phrase Match Example

    action=Query&Text="fresh and lovely"

IDOL Server removes any stop words that the query contains (the example query above contains the stop word and) but it returns only documents that contain the phrase with the exact terms that you specify. It matches as if the query is:

    action=Query&Text="fresh lovely"

When it matches the query, 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).
