Splunk Search

Error in 'UnifiedSearch': Unable to parse the 'Missing LHS for AND' search --> error when searching for surrounding events - why?

Does anyone know why I am getting the following error when running the following search to find surrounding events:

* [ search sourcetype=fireeye OR sourcetype=imap | eval starttimeu=_time | eval endtimeu=_time+300 | fields + starttimeu endtimeu ]

(Seen on Splunk search head version 4.1.5)

Because the implicit format of the subsearch inserts the AND keyword, making the result of your subsearch ((starttimeu="1234567590" AND endtimeu="1234567890")). Splunk syntax doesn't like the AND with time quantifiers. I personally consider this a bug.

Also, starttimeu and endtimeu have been deprecated for some time now. Please use earliest and latest instead.

The fix/workaround is to use and explicit format that doesn't insert the AND (which isn't necessary anyway):

* [ search sourcetype=fireeye OR sourcetype=imap | eval earliest=_time | eval latest=_time+300 | fields earliest latest | format "(" "(" " " ")" "OR" ")" ]

Another workaround for this is to perform two sub-searches in succession, one of the earliest and one for the latest time values, like this:

  • [search sourcetype=syslog error |eval endtimeu = _time+300 | fields + endtimeu] [search sourcetype=syslog error |eval starttimeu = _time-300 | fields + starttimeu]
