Hi all,
I have been using the Pinecone metadata filters by using the Langchain Self-Query Retriever. This has been really helpful for applying hard filters on my inventory while also doing embedding similarity in one query.
One issue I have run into is applying the hard filters on string attributes. My datasets tagging can be a bit variable. For example, if I have a piece of clothing inventory with an attribute style, the values can vary but have the same meaning. One example is an item could be tagged as Style == button-down or Style == button downs. I realize that there are ways to improve my attribute tagging; however, I am wondering if there is any chance that a filtering capability for strings that does prefix/suffix matching and/or does a similarity match is in the works (if possible).
Any input on this issue including alternate ways to address this problem is much appreciated.
Thanks,
Ben
