This is a major step because solr removed support for embedded solr
instances in 9.0 and we want to keep it because we want to ship
YaCy with an embedded solr. It was necessary to add parts of solr
code into YaCy to make this migration possible. Further on with
Solr 9.1 they removed even more parts which are required for embedded
operation, therefore we cannot migrate yet further without big
changes.
If you are running a YaCy instance with Solr 8.x, the migration should
be done automatically. If not you require to first migrate to a YaCy
version 1.93 with Solr 8.x to migrate to Solr 8 data.
webgraph. These cores are now accessible at
/solr/collection1/select instead /solr/select?core=collection1
and
/solr/webgraph/select instead /solr/select?core=webgraph
in addition to the old behavior to support compatibility to the old
peers. These new paths are fully solr standard-conform and will allow
the cross-linking between YaCy peers using their public solr API.
- since specific heuristic Twitter & Blekko is not longer available or redundant with OpenSearchHeuristic,
adjusted ConfigHeuristic to use OpensearchHeuristic settings only.
For this the default OSD search target list is made available (copied) by default and the other configs are removed.
- the return of QueryGoal.getOriginalQueryString includes the queryModifier, which are held separately in a modifier object,
but in most (all) cases just the query term is expected, clarified and renamed it to QueryGoal.getQueryString which returns
just the search term (if needed a .getOrigianlQueryString could be implemented in Queryparameters, adding the modifiers)
- started to adjust internal html href references from absolute to relative (currently it is mixed).
For future development we should prefer relative href targets (less trouble with context aware servlets)
