Filtering in Query Engine using ismatch

Hi, is there any way to filter in a query_engine using a ismatch like u can do in the normal search? i need to do a regex filter like "search.ismatch('/,.{group},./', 'groups', 'full', 'any')", the field groups is a comma separated field.

This example is for Qdrant Metadata filtering: https://docs.llamaindex.ai/en/stable/examples/vector_stores/Qdrant_metadata_filter/#qdrant-vector-store-metadata-filter

For filtering llamaindex provides the following operators: https://github.com/run-llama/llama_index/blob/227145fb94fcaa4da02d559fc81843fcb2af2b57/llama-index-core/llama_index/core/vector_stores/types.py#L63

You can check which one suits your need

does the TEXT_MATCH do like regex or lucene parsing cause i dont want it to do partial matches.

also didnt understood the qdrant filtering

MetadataFilter(key="groups", value="group1", operator=FilterOperator.TEXT_MATCH )
groups = "group1,group2"
like this
