Searching for One Character Words in Index Server (174777)



The information in this article applies to:

  • Microsoft Index Server 1.1

This article was previously published under Q174777

SYMPTOMS

When you search for a string, for example, "C++" (without the quotes), Index Server will return the following error message:
The query contained only ignored words. (0x80041605) encountered
while processing the query "c++".

CAUSE

Both the neutral and English wordbreakers strip the trailing "++" characters, because they are not part of a linguistic word.

An escape feature exists for special characters such as "&" and "|", because they have special meaning in the query syntax. However, the "+" character has no such special meaning.

Also, even with escapes, the query "c(" will be converted to "c", which is a noise-word-only query.

RESOLUTION

This problem is corrected in Windows 2000 Indexing Service. Any words ending with ++, +, - and ! are passed to the engine and not considered noise words. To resolve this problem, upgrade to Windows 2000 Indexing Service.

WORKAROUND

Remove the letter "c" from the noise files: Noise.enu and Noise.dat. In that case searching for "c++" will be the same as searching for the letter "c".

NOTE: After you edit the noise files, you will need to reindex all of the virtual roots.

STATUS

This problem is corrected in Windows 2000 Indexing Service.
