expression templates not supported #327
Description
Expression Templates (https://milvus.io/docs/v2.5.x/filtering-templating.md) are not supported in mulvus-lite as of version 2.5.1.
The documentation lists it as a feature available in 2.5, and it's not mentioned in the list of limitations in the milvus-lite readme
Moreover I see this as an essential feature. If I have untrusted inputs (like file names) I now have to do some kind of fragile quoting like it's 2004. This is an SQL injection waiting to happen. I don't think I can in good conscience ship anything with milvus-lite while this feature is missing
