> Key: SOLR-4056
> URL: https://issues.apache.org/jira/browse/SOLR-4056
> Project: Solr

> Affects Versions: 3.6.1
> Reporter: Siegfried Goeschl
> Priority: Minor
> Fix For: 3.6.3
>
>
> I'm now finishing a SOLR project for one of my customers (replacing Microsoft
> FAST server with SOLR) and got the permission to contribute our improvements.
> The most interesting thing is a "FrequentSearchTerm" component which allows
> to analyze the user-supplied search queries in real-time
> * it keeps track of the last queries per core using a LIFO buffer (so we
> have an upper limit of memory consumption)
> * per query entry we keep track of the number of invocations, the average
> number of result document and the average execution time
> * we allow for custom searches across the frequent search terms using the
> MVEL expression language (see http://mvel.codehaus.org)
> ** find all queries which did not yield any results - 'meanHits==0'
> ** find all "iPhone" queries - "searchTerm.contains("iphone) ||
> searchTerm.contains("i-phone)''
> ** find all long-running "iPhone" queries - '(searchTerm.contains("iphone)
> || searchTerm.contains("i-phone)) && meanTime>50'
> * GUI : we have a JSP page which allows to access the frequent search terms
> * there is also an XML/CSV export we use to display the 50 most frequently
> used search queries in real-time
> We use this component
> * to get input for QA regarding frequently used search terms
> * to find strange queries, e.g. queries returning no or too many result,
> e.g. caused by WordDelimeterFilter
> * to keep our management happy ... :-)
> Not sure if the name "Frequent Search Term Component" is perfectly suitable
> as it was taken from FAST - suggestions welcome. Maybe
> "FrequentSearchQueryComponent" would be more suitable?
