ICS.IndexExists

Checks for the existence of a search index.

Syntax

public boolean 
IndexExists(String sIndex,
            String sEngine,
            String sCharset,
            StringBuffer sbError)

Parameters

sIndex

Full pathname of search index to find.

sEngine

Search engine name. If null, the value of the Content Server property, cs.searchengine, is used.

sCharset

Constant value representing the character set the index uses. For the AltaVista search engine, this value can be 0, 1, or 2 (ASCII7, ASCII8 (Not supported), or UTF8). If sCharSet is null, Content Server uses the value of av.charset in the properties file.

sbError

For return values; may contain error information.

Returns

Returns true if the index exists, false otherwise.

Errno

Use GetErrno (), and see Appendix A, "Error Conditions," for the possible errno values.

Example

The following example checks for the existence of an index:

ics.ClearErrno();
StringBuffer errs = new StringBuffer();
ics.IndexExists("D:/myIndex", null, null, errs);
int existsErrno = ics.GetErrno();
