The amount of announcements in our database is so large, that our web site users started to look for another option to filter search results and another way of sorting them. We need to add the functionality, which allows us to operate with localization data related to the cars.
In the first part of our ”Car sale” application related posts we created some standard index structure by properly configuring schema.xml configuration file. It didn’t take long to hear the first complains from the website users with this kind of configuration. Why don’t I receive any search results entering the “audi a” phrase ? I would like to see some announcements with “Audi A6” and “Audi A8” for example. I entered the phrase “Honda crv” – 0 results, “Suzuki maruti” – none. Are there no related offers in the announcement database ? There are! But the current configuration of the searchable field type (field “content” – type “text”) does not allow us to find those offers using the queries we’ve entered. That’s the reason why the WordDelimiterFilter and PatternReplaceFilter need to enter the battlefield.
One of the fundamental solr’s configuration file is the schema.xml file. It is a kind of connector between what we need and what solr understands. If we want to have a search engine, that gives us search results we really expect, then it is very important to properly design the schema.xml configuration file.
We would like to introduce you the first of the series of articles which will hopefully show us how to design schema.xml file and how to handle and modify all of the file’s components.
