: assuming I've written the subclass of the postings format, I need to tell : Solr to use it. : : Do I just do something like: : : <fieldType name="ocr" class="solr.TextField" postingsFormat="MySubclass" />
the postingFormat xml tag in schema.xml just refers to the "name" of the postingFormat in SPI -- which is discussed in the PostingFormat javadocs... https://lucene.apache.org/core/4_10_0/core/org/apache/lucene/codecs/PostingsFormat.html ...the nuts & bolts of it is that the PostingFormat baseclass should take care of all the SPI "name" registration that you need based on what you pass to the super() construction ... allthough now that i think about it, i'm not sure how you'd go about specifying your own name for the PostingFormat when also doing something like subclassing Lucene41PostingsFormat ... there's no Lucene41PostingsFormat constructor you can call from your subclass to override the name. not sure what the expectation is there in the java API. : Is there a way to set this for all fieldtypes or would that require writing : a custom CodecFactory? SchemaCodecFactory uses the Lucene default for any fieldType that doesn't define it's own postingFormat -- so if you wnated to change the postingFormat or *every* fieldType, then yes: you'd need to override the CodecFactory itself. -Hoss http://www.lucidworks.com/
