>Sometimes we need to only re-index a subset of our bibliographic data or authorities. Currently this is only possible by enumerating all id (-bn or -ai), which does not work well when indexing eg 100.000 items of a 2.000.000 DB. Re-indexing everything is also overkill.
>
>This patch adds an `--where` flag to misc/search_tools/rebuild_elasticsearch.pl which can take arbitrary SQL (that of course has to match the respective tables) and adds it as an additional param to the resultset to index
>
>To test, start koha-testing-docker with ElasticSearch enabled, for example via `ktd --es7 up
>
>Before applying the patch, rebuild_elasticsearch will index all data:
>
>Biblios:
>$ misc/search_tools/rebuild_elasticsearch.pl -b -v
>[12387] Checking state of biblios index
>[12387] Indexing biblios
>[12387] Committing final records...
>[12387] Total 435 records indexed
>(there might be a waring regarding a broken biblio, which can be ignored)
>
>Auth:
>$ misc/search_tools/rebuild_elasticsearch.pl -a -v
>[12546] Checking state of authorities index
>[12546] Indexing authorities
>[12546] 1000 records processed
>[12546] Committing final records...
>[12546] Total 1706 records indexed
>
>Now apply the patch
>
>Biblio, limit by range of biblioid:
>$ misc/search_tools/rebuild_elasticsearch.pl -b -v --where "biblionumber between 100 and 150"
>[12765] Checking state of biblios index
>[12765] Indexing biblios
>[12765] Committing final records...
>[12765] Total 50 records indexed
>
>Note that only 50 records where indexed (instead of the whole set of 435 records)
>
>Auth, limit by authtypecode:
>$ misc/search_tools/rebuild_elasticsearch.pl -a -v --where "authtypecode = 'GEOGR_NAME'"
>[12848] Checking state of authorities index
>[12848] Indexing authorities
>[12848] Committing final records...
>[12848] Total 142 records indexed
>
>Again, only 142 have been indexed.
