Upgrade to Solr 9.1.x #242

Open DiegoPino opened 1 year ago

DiegoPino commented 1 year ago

What?

As documented here https://github.com/apache/lucene/commit/98dafe2e1047cdfe8ed8bbfb444fab2798193a9f Solr 8/Lucene 8 has a long standing bug that affects our Community (Librarian/Museum) needs for very complex exact matches.

This binds with https://github.com/esmero/strawberryfield/issues/263

Changes needed are: New OCR highlight component (moving to 0.8.4), Solr Field types, Schema, Config and core.conf changes. Upgrade itself does not imply loosing data but a reindex is encouraged

Plus code changes to avoid the Solr 9 defaults that don't play with Search API Solr.

I have all tested locally. Will clean, package and make a pull against 1.1.0

This is done, but we have no perfect step by step documentation. Being really the simples way to backup your core. Clear your core, get the new configs + the new OCR library, replace the container and start it again. Then re-index. Honestly that is the only way. But will keep this open I find time to document or someone in the community gives us a hand
