Store.IsInstantSearchEnabled property (Outlook)

  • Article

Returns a Boolean that indicates whether Instant Search is enabled and operational on a store. Read-only.

Syntax

expression. IsInstantSearchEnabled

expression A variable that represents a Store object.

Remarks

Use IsInstantSearchEnabled to evaluate whether you should use ci_startswith or ci_phrasematch operators in your query. If you use ci_startswith or ci_phrasematch in the query and Instant Search is not enabled, Outlook will return an error.

Example

The following code sample accepts a matching string as an input parameter, constructs a DASL filter with the content indexing keyword ci_phrasematch if Instant Search is enabled on the store, and returns the filter. Otherwise, if Instant Search is not operational, then the code sample returns a filter that uses the like keyword.

For more information on filtering with keywords, see Filtering Items Using Query Keywords.
