Solr 4.0: new fl parameter functionalities – first look
In connection with the work of slowly upcoming release of Apache Solr version 4.0 I thought that it is time to bring some light on the functionalities that you will get into your own hands with the release of Apache Solr 4.0.

Lucene Eurocon 2011 – day two
Lucene Eurocon 2011 – day one
As we wrote a few days ago we are back from this year Lucene Eurocon, which took place in Barcelona. Despite the fact that the videos will be available shortly, we decided to wrote something about those presentations we attended to.
Near future plans
Surely you noticed a decreased activity of solr.pl. But this is not related to preparations for winter sleep. We are not bored also.

Lucene and Solr 3.4
Today, we can enjoy another version of Lucene and Solr – release numbered 3.4. In the newest version there are a few functionalities worth looking at.
Optimization – document cache
Deep paging problem
Imagine the following problem – we have an application that expects Solr to return the results sorted on the basis of some field. Those results will be than paged in the GUI. However, if the person using the GUI application immediately selects the tenth, twentieth, or fiftieth page of search results there is a problem – the wait time. Is there anything we can do about this? Yes, we can help Solr a bit.
“Car sale application”– Result Grouping, let’s group some search results (part 6)
In today’s post we will try to add to our car sale application the new functionality, which allows us to group some search results. Let’s imagine a user who would like to search for “audi a4” advertisements and as a result get the results grouped by car’s year of production, with 2-3 results in every group. And how about some range grouping, for example mileage ranges? Today we will accept the challenge.
