grn_expr
========
`grn_expr` is an :c:type:`grn_obj` that represents an expression. Here
is a list of what expression can do:
* Expression can apply some operations to a record by
:c:func:`grn_expr_exec`.
* Expression can represents search condition. :c:func:`grn_table_select`
can select records that match against the search condition represented
by expression.
There are two string representations of expression:
* :doc:`/reference/grn_expr/query_syntax`
* :doc:`/reference/grn_expr/script_syntax`
:c:func:`grn_expr_parse` parses string represented expression and
appends the parsed expression to another expression.
