If you don't want to use regular expressions, enclose your search\nin double quotation marks ( \" ). For example: \n\n \"foo()\" # Treats the parentheses as literals. Doesn't match 'food'.\n foo() # Parentheses are treated as part of a regular expression. Matches 'food'.\n\n| **Note:** If you use a [search filter](../reference/#filters), such as `file`, don't enclose the filter in quotes. For example, use `file:abd.xyz` not `file:\"abc.xyz\"`.\n\nCross references\n----------------\n\n[Cross references](/code-search/user/cross-references) are available for some repositories.\nWhere cross references are enabled, symbols are links to their definition.\nClicking a symbol definition shows a list of usages.\n\nWhat's next\n-----------\n\n- Search for [files](../user/search-files) or [file contents](../user/search-file-contents).\n- Learn about supported operators, filters, and keyboard shortcuts in the Code Search [reference](../reference) documentation."]]
