One of our readers reported a very interesting problem, which can be summarized to the following question – “Why doesn’t ReversedWildcardFilterFactory doesn’t work with Polish letters ?”. This entry will attempt to answer this question.
Faceting, filters elimination and how to use it ?
During my everyday work, I have seen many repeated queries, to Solr, with only one filter difference. When I asked why – I got anserws that it was necessary to get the faceting results for various filters. If you are using Solr version 1.4 or later, my suggestion is to use local params – what is it and how to use – this post will attempt to answer both questions.
Lucene 3.0.3 and Lucene 2.9.4
A few minutes ago Uwe Schindler announced that there are two new versions of Lucene library available:
Solr and autocomplete (part 3)
Data Import Handler – How to import data from SQL databases (part 3)
Solr and autocomplete (part 2)
In the previous part I showed how the faceting mechanism can be used to achieve the autocomplete functionality. Today I’ll show you how to use a component called Suggester to implement autocomplete functionality.

Data Import Handler – How to import data from SQL databases (part 2)
In the first part we were able to index the information contained in the database. In the second part we will try to extend the functionality by adding incremental imports.
Hierarchical faceting – Pivot facets in trunk
In a large number of implementations which I took part in, sooner or later, the question arise – what can we do to get faceting as a tree structure. Of course there some tricks for that, however, their use was to modify the data and appropriate processing of the results on application side. It was not particularly functional, nor especially comfortable. However, a few days ago Solr version 4.0 has been enhanced with code that is marked as Solr-792 in the system JIRA. Let’s see in this case, how to get the faceting results as a tree.
Solr and autocomplete (part 1)
Almost everyone has seen how the autocomplete feature looks like. No wonder, then, Solr provides mechanisms by which we can build such functionality. In today’s entry I will show you how you can add autocomplete mechanism using faceting.
