Because Polish language analysis functionality is present in Lucene (and Solr) for some time I decided to take a look and compare it on the basis of upcoming Lucene and Solr 4.0.
The next functionality I decided to look at, from the upcoming Solr 4.0, is the so called “Realtime Get”. It allows you to see the data even though it was not yet added to the index, thus before the commit operation being sent to Solr. Let’s see how it works.
In todays entry we will look at the next feature that will come with version 4.0 of Apache Solr. We will look at the functionality which enables us to modify the fields in Solr result list.
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.
FieldCollapsing, or in other words grouping of search results has just been commited to the svn repository. I decided to take a look at this functionality and see how it works.
