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:
1 2 3 4 5 6 7 8 9 10 11 12 13
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.
