Use query in the documentation

Review documentation and ensure that we use query throughout the documentation.

Point out that an user can use masking if wanted. I suggest one example in the Section 1.5. Row filtering (e.g. .query) comparing the synatx of these two options. Add this part to Section 1.5 if it does not exist already.

Start by reviewing the documentation around Section 1.5, “Row filtering (e.g. .query),” and search the rest of the docs for inconsistent query terminology. Check whether the masking note and comparison example already exist; done means terminology is consistent, masking is explained as optional, and the two syntax options are compared in Section 1.5.
