nsslapd-search-tune

Skip check for modifications during search before returning entries

Description

PROPERTY	VALUE
Entry DN	cn=config,cn=ldbm database,cn=plugins,cn=config
Valid Range	See description that follows.
Default Value	Not defined
Syntax	Integer

This attribute specifies that Directory Server should skip the double-check it normally does to verify that search results returned include the most current version of the entry content, even if the entry has been modified during the search. This double-check verification involves testing the search filter against each entry to return in response to the search.

Allowing Directory Server to skip the filter test when the search involves complex filters and large static groups can result in significant performance improvement.

When nsslapd-search-tune is set, the access log identifies searches for which the filter test is skipped with the tag notes=F.

Set nsslapd-search-tune to a sum of the following values:

1

Enable the filter test to be skipped before the entry is returned.

2

Reserved, do not use.

4

Reserved, do not use.

8

Skip the filter test even if the attribute in the filter is in the list of requested attributes. This could potentially cause the server to return entries that no longer correspond to search criteria.

16

Skip the filter test when search filters are complex, using & and |.

32

Always finish building the list of candidate entries from the index.
