supported match predicate is `eq?` (both comparing a capture against a string
and two captures against each other).
+A `query` consists of one or more patterns. A `pattern` is defined over node
+types in the syntax tree. A `match` corresponds to specific elements of the
+syntax tree which match a pattern. Patterns may optionally define captures
+and predicates. A `capture` allows you to associate names with a specific
+node in a pattern. A `predicate` adds arbitrary metadata and conditional data
+to a match.
+
vim.treesitter.parse_query({lang}, {query})
*vim.treesitter.parse_query()*
Parse {query} as a string. (If the query is in a file, the caller
should read the contents into a string before calling).
+ Returns a `Query` (see |lua-treesitter-query|) object which can be used to
+ search nodes in the syntax tree for the patterns defined in {query}
+ using `iter_*` methods below. Exposes `info` and `captures` with
+ additional information about the {query}.
+ - `captures` contains the list of unique capture names defined in
+ {query}.
+ -` info.captures` also points to `captures`.
+ - `info.patterns` contains information about predicates.

query:iter_captures({node}, {bufnr}, {start_row}, {end_row})
*query:iter_captures()*
Iterate over all captures from all matches inside {node}.
