/* For understanding how text matching in Sanity GROG works: refer https://www.sanity.io/docs/query-cheat-sheet#170b92d4caa2
    Basically our 1st query returns all pins whose title/category/about starts with the "searchTerm" word.

    But we don't want each and every field, so we can project the fields we want (This property is similar to GQL and advantage over REST).
    In our Case, the fields of each pin we want are: [For Docs refer: https://www.sanity.io/docs/how-queries-work]
    1. _id , 2. image [image is a special Sanity type which has an asset reference field and form that we just want the url field hence the given syntax used]. -> is dereferencing operator which allows to populate the fields of reference otherwise only reference id is returned (in our case, we wanted url from asset),
    3. destination, 4.postedBy(since it is ref, we dereferenced the required fields from it),
    5. save (since it is an array,we add [] after the name and from that we want only postedBy and key which is unique for array element generated by Sanity, hence _ before it).
