5.1.2.13. Unindexed Search Indicator

The unindexed search indicator, notes=U, indicates that the search performed was unindexed,
which means that the database itself had to be directly searched instead of the index file. Unindexed
searches occur in three scenarios:
• When the nsslapd-idlistscanlimit was reached within the index file used for the search.
• When no index file existed.
• When the index file was not configured in the way required by the search.
NOTE
An unindexed search indicator is often accompanied by a large etime value, as
unindexed searches are generally more time consuming.
5.1.2.14. VLV-Related Entries
When a search involves virtual list views (VLVs), appropriate entries are logged in the access log file.
Similar to the other entries, VLV-specific entries show the request and response information side by
side:
VLV RequestInformation ResponseInformation
RequestInformation has the following form:
beforeCount:afterCount:index:contentCount
If the client uses a position-by-value VLV request, the format for the first part, the request information
would be beforeCount: afterCount: value.
ResponseInformation has the following form:
targetPosition:contentCount (resultCode)
The example below highlights the VLV-specific entries:
[07/May/2007:11:43:29 -0700] conn=877 op=8530 SRCH base="(ou=People)" scope=2 filter="(uid=*)"
[07/May/2007:11:43:29 -0700] conn=877 op=8530 SORT uid
[07/May/2007:11:43:29 -0700] conn=877 op=8530 VLV 0:5:0210 10:5397 (0)
[07/May/2007:11:43:29 -0700] conn=877 op=8530 RESULT err=0 tag=101 nentries=1 etime=0
In the above example, the first part, 0:5:0210, is the VLV request information:
• The beforeCount is 0.
• The afterCount is 5.
