7.26.11. grn_expr

grn_expr is an grn_obj that represents an expression. Here is a list of what expression can do:

• Expression can apply some operations to a record by grn_expr_exec().

• Expression can represents search condition. grn_table_select() can select records that match against the search condition represented by expression.

There are two string representations of expression:

• Query syntax

• Script syntax

grn_expr_parse() parses string represented expression and appends the parsed expression to another expression.
