Last day just after I hit the “submit” button a doubt came into my mind: “did I say everything ?” Well, the answer is “No!” In fact I forgot to tell you one of the most important things: how to have some fun with Strigi and Xesam! Actually the only way to perform XesamQueryLanguage queries with Strigi is through the strigicmd program.

Strigicmd is a command-line tool shipped with Strigi. It can perform different actions like:

• create Strigi indexes
• remove items from index
• list all files contained into an index
• retrieve informations associated to an indexed file
• update the contents of your index
• query the index
• perform a query using XesamQueryLanguage

So, if you want to try the new Xesam support you’ve just to use strigicmd with the xesamquery option. The command syntax is: strigicmd xesamquery -t backend -d indexdir [-u xesam_user_language_file] [-q xesam_query_language_file] As you can expect you’ve to save your Xesam query to file and point strigicmd to it.

This is a really small step-by-step guide:

• Create a new Strigi index (in this case I’ll index all irc logs): strigicmd create -t clucene -d temp/ logs/

• Create a simple file containing your Xesam query. You can find some example query on Xesam site or inside strigi tarball (complete path: strigi/src/streamanalyzer/xesam/testqueries/). This is a stupid and easy query:

  {% codeblock [query] [lang:xml ] %} Oever jos {% endcodeblock %}

• Perform the search, just type:

  strigicmd xesamquery -t clucene -d temp/ -q ~/irc_oever.xml

• Enjoy the search results ;)

Remember that XesamUserLanguage query language isn’t yet supported.
