They will continue to run until all results are found that have been specified by your search query. So for example, the above query, "index=*" it will search all indices without any fields filtering out the results, thus having a longer run time. </P> Thu, 25 Sep 2014 23:29:32 GMT ben_leung 2014-09-25T23:29:32Z https://community.splunk.com/t5/Splunk-Search/How-long-does-the-ad-hoc-search-run/m-p/198366#M57342 <P>Hi Splunkers,</P> <P>Priviously our search head were down with 100% CPU and memory used.<BR /> That was caused by background searches like below which continues to run over 24 hours.</P> <PRE><CODE>index=* </CODE></PRE> <P>Now I know the way to stop and suspend background searches,<BR /> but I don't know specifically that what situations ad hoc searches continue to run.</P> <P>Do ad hoc searches continue to run until that get the results ?</P> <P>Thank you for your help.</P> Sun, 15 Jun 2014 07:06:57 GMT https://community.splunk.com/t5/Splunk-Search/How-long-does-the-ad-hoc-search-run/m-p/198366#M57342 sunrise 2014-06-15T07:06:57Z https://community.splunk.com/t5/Splunk-Search/How-long-does-the-ad-hoc-search-run/m-p/198367#M57343 <P>When running ad hoc searches, you should specify the time range, other wise you might be searching all-time, which causes load and is not really productive in my opinion.
