I was passing the search string entered by the user directly to 
searchResults() and didn't thought about trying this. I've resolved the 
problem quoting the words in the string.

It worked using grok.index.Value. By the way, I'm not sure, but it seems 
like the documentation of Value and Set should be exchanged.

Oh! I missed the second one. I'm so desperate for documentation that I'm 
even looking at this kind of documentation through different eyes ;-)

Thanks a lot for the help!
