Stax-API jar
Hi Folks, I think I've identified a bug in stax-api-1.0.jar. Specifically javax.xml.stream.XMLStreamReader::getTextStart(). I'm just wonder who owns/manages the source of the implementation that Solr uses? https://stax-utils.dev.java.net/ gives four implementations, I just need to know which one so that I can take up my issue in that space. Is there any easy way to tell? Tricia

Re: Stax-API jar
also note -- if you are using java6, you can remove the two stax jars and use the default implementation.

Is there a built in keyword report (Tag Cloud) feature on Solr ?
I am developing a Solr based search application and need to get a kind of a keyword report for tag cloud generation. If there is anyone here who has ever had that necessity and has somehow found the way through, I would really appreciate some help.

Re: Is there a built in keyword report (Tag Cloud) feature on Solr ?
A solution that I'd considering implementing for Drupal's ApacheSolr module is to do a *:* search and then make tag clouds from all of the facets. Pretty easy to sort all the facet terms into bins based on the number of documents they match, and then to translate bins to font sizes. Tag clouds make a nice alternate representation of facet blocks.

Re: Is there a built in keyword report (Tag Cloud) feature on Solr ?
Thanks the help "... do a *:* search and then make tag clouds from all of the facets ..." I may have not made myself clear. When I say keyword report, I mean a kind of a most popular tag cloud, showing in bigger sizes the most searched terms. Therefore I need information about how many times specific terms have been searched and I can't see how I could accomplish that with this solution Walter Underwood wrote: > > Oops, missed that you wanted it by facet.

Re: Is there a built in keyword report (Tag Cloud) feature on Solr ?
If you want a tag cloud based on query freqency, start with your HTTP log analysis tools. Most of those generate a list of top queries and top words in queries. wunder On 2/26/09 2:54 PM, "Chris Hostetter" wrote: > > : I may have not made myself clear.

Re: Is there a built in keyword report (Tag Cloud) feature on Solr ?
Sorry for that. Most searched terms tag cloud is kind of common around here. "Solr doesn't keep any record of the searches performed, so to build a tag cloud based on query popularity you would need to mine your logs." Do you know if there is already a tool or a Solr plugin for that ? Thanks hossman wrote: > > > : I may have not made myself clear.

Re: Is there a built in keyword report (Tag Cloud) feature on Solr ?
To do that, your best option is to do it "outside" of solr. I.e., when someone enters a query in your webapplication, you store the search in for instance a db (or even in a separate solr-index). If you go with a solr-index for "queries", you can simply do facets on the queries and for instance a facet.limit=50 (which will give you the top 50 most frequently entered queries). - Aleksander On Thu, 26 Feb 2009 19:35:49 +0100, Emmanuel Castro Santana wrote: Thanks the help "... do a *:* search and then make tag clouds from all of the facets ..."

Re: Is there a built in keyword report (Tag Cloud) feature on Solr ?
Sorry, that mail got stuck in my outbox. Anyways. On a side-note, i think it is called a search-cloud when refering to top-searches, and a tag-cloud when refering to top-occuring terms in the corpus, as Chris said. Since you are only after creating a search-cloud, i think my answer is a pretty straightforward and simple (and fast) approach to doing so. And as Chris mentions, if you want to create a tag cloud with those words that are a.) occuring frequently in the corpus, or b.) more advanced, those terms that are actually "important" to your corpus (score-based / tf-idf etc.) you can simply use the TermsComponent. As the trunk version of Solr introduces the TermVectorComponent, you can also retrieve information for specific search-results etc. Another thing you could do with your search-cloud is to for instance add a date-dimension to the solr-index (where you store all the queries), and then out of the box you get the possibility of creating evolving-search-clouds! I.e., you can visualize how "what is being searched for" changes over time! -> now thats a neat feature :) And best of all - Solr gives you this for free with facets once you have those queries indexed :) Hope that helps!
