XpoLog help - XpoSearch
 

XpoSearch is an integrated search engine that enables extremely fast searches on large files. Using XpoLog's automation mechanism, XpoSearch constantly updates the indices of logged data to keep search results accurate. You can also index a log manually. The size a log's index is roughly 20% of the log's size, and it takes about 15 minutes to index 1 Gigabyte of log.
Whenever you perform a search on a log or activate a filter on a log, either in the log view or anywhere else in the system, XpoLog first checks whether the log is indexed; in case it is, the search engine delivers the search results in a matter of milliseconds.
