One of the new features, which will be introduces with Solr 4.0 is a new SpellChecker implementation, which doesn’t require its own index. I decided to take a quick look at it and share my thoughts.
Explain: new version
We are proud to inform that we deployed a new version of explain.solr.pl, software for debugging and analyzing Solr queries. This version contains the following changes:
- bugfixes
- initial support for dla Solr 4.0
- support for ruby 1.9
Source code is available on our GitHub.
Apache Lucene and Solr 3.6
Solr 4.0 and Polish language analysis
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.
Solr 3.6: CurrencyField
The incoming Solr 3.6 will bring us an interesting feature in the form of currency handling. Some may ask “What for ? We can just use float and we can use it for currency handling”. So let’s take a look at solr.CurrencyField which will be presented in Solr 3.6.
Use of cache=false and cost parameters
explain.solr.pl as Open Source!
As we promised earlier, source code for explain.solr.pl is now published.
Simple photo search
Recently we had a change to help with a non-commercial project which included search as its part. One of the assumptions, although not the key ones, was the photo search functionality, so that the user could find the pictures fast and accurately. Because the search had to work with meta data of JPEG files, the idea was simple – use Apache Solr with Apache Tika.
What can we use Dismax tie parameter for?
Dismax query parser have been with Solr for a long time. Most of the time we use parameters like qf, pf or mm forgetting about a very useful parameter which allows us to control how the lower scoring fields are treated – about the tie parameter.
