[TYPO3-Solr] Exclude Columns from indexing

[Stephan Schuler]

Hey there.


I'm not completely aware of all of its implications in reference to tx_solrs inner mechanics, but you could try to use Solrs Result Grouping and Field Collapsing feature.


Add those query parameters to the search query:
&group=true&group.field=id&group.limit=1&group.format=simple&group.main=true

This should do something like "SELECT * FROM solr GROUP BY id", and the "id" property contains both, the records database table name and UID.

Unfortunately the grouping feature only exists in Solr 3.3 and higher. Currently the tx_solrs extension is based on Solr 2.5 where no grouping is available. Feel free to give Solr 4 a try and see if it works.


Having duplicates stored to the Solr core should not be a huge problem since Solr stores data very efficiently. Multiple rows that differ only very little should not use much more disk space then a single of those rows.

there is currently noone as this is designed behaviour to prevent to expose content to people not entitled to see it.

maybe with apache solr server 4.x there might be a way to remove those duplicates.

until then you will need to live with this cosmetic issue.
