Step 3 : Understanding the addObject method
The addObject (/search/plugins/ezsolr/ezsolr.php) method takes the following parameters :
- One single content object (eZContentObject)
- An optional parameter, indicating whether the freshly added content should be followed by a 'commit' (this is, by the way, a very good way to optimize batch-indexings of content)
In brief, this methods acts as follows :
- Checks whether the content object should be indexed or not, according to the list of excluded content classes (settings : [IndexExclude])
- Retrieval of the objects's metadata and creation of names and values for the associated Solr fields
- Retrieval of the node's metadata and creation of names and values for the associated Solr fields
- Retrieval of the object attributes' content, for each language, and creation of names and values for the associated Solr fields
- Push of the collected data to Solr's index, in single or multi-core mode, depending on the settings
- Final commit, conditioned by the second, optional parameter of the addObject method
Note : since eZ Find 2.2, it is possible to use language-specific 'cores' (/extension/ezfind/java/solr.multicore), allowing for having per-language indexes and configuration files (spellings.txt, synonmys.txt, stopwords.txt, etc.).
