PRB: Searching Phrases with Numbers in MSIDXS OLE DB Provider (179237)


The information in this article applies to:

  • Microsoft OLE DB Provider for Index Server 2.0
  • Microsoft Data Access Components 2.1
  • Microsoft Data Access Components 2.5
  • Microsoft Data Access Components 2.6
This article was previously published under Q179237

SYMPTOMS

When using ActiveX Data Objects (ADO) with the OLE DB Provider for Index Server (MSIDXS) to query the contents of Index Server and you use a phrase where the first word starts with a number, Index Server may return incorrect hits. For example, when you search for the phrase '"32MB RAM"', Index Server may produce extra hits containing documents with just "RAM". The query '"32MB and RAM"' works correctly. Searching for other phrases such as '"SQL Server"' also works correctly.

CAUSE

This is a problem in the Index Server 2.0 query mechanism. Using an HTX/IDQ sample reproduces the same behavior.

RESOLUTION

You can work around this problem by adding an additional word to the beginning of the phrase (for example, CONTAINS('"the 32MB RAM"') > 0 ). The following query works correctly:

SELECT Filename, Path, Size, Write FROM Scope('"/"') WHERE CONTAINS('"the 32MB RAM"') > 0

STATUS

Microsoft is researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.

MORE INFORMATION

Steps to Reproduce Behavior:

Use ADO and the MSIDXS provider to submit the following query with different search phrases:

SELECT Filename, Path, Size, Write FROM Scope('"/"') WHERE CONTAINS('"32MB RAM"') > 0 ORDER BY Filename

  1. Search for CONTAINS('"32MB"') > 0 and the hits will be correct.
  2. Search for CONTAINS('"32MB RAM"') > 0 and it hits the documents containing the phrase "32MB RAM". However, this query also hits many other documents containing the word "RAM", but without the phrase "32MB RAM".
  3. Search for CONTAINS('"32MB and RAM"') > 0 and it hits the correct number of documents containing the word "RAM" and "32MB" that may occur together or at different places in the documents.
