[GitHub] [pinot] itschrispeck opened a new issue, #10975: Text Index does not match against mutable segments for MV Columns
itschrispeck opened a new issue, #10975:
URL: https://github.com/apache/pinot/issues/10975
### Problem
I'm querying a column via text_match that is a MV String column. This results in partial results as consuming segments cannot be matched on. Looking into this, the cause appears to be that text index on MV columns for mutable segments [is not yet supported](https://github.com/apache/pinot/blob/master/pinot-segment-spi/src/main/java/org/apache/pinot/segment/spi/index/mutable/MutableTextIndex.java#L34).
I looked at adding this, but since the MV noDict implementation is missing for mutable var-width segment types it wasn't simple to replicate the implementation for creating a text index on SV noDict columns.
I'm curious to get others' input on implementation options. Whether that's through supporting text index on dictionary encoded cols (for mutable segment only/for MV col only/etc), waiting for [support for the noDict implementation for mutable var-width column types](https://github.com/apache/pinot/blob/master/pinot-segment-local/src/main/java/org/apache/pinot/segment/local/segment/index/forward/ForwardIndexType.java#L293C18-L293C18), or something else.
