List of Reserved Characters in UQL

If you need to use them as words in your query, you must enclose them in quotes.


Name	Character
Slash	`/` Use it for: passing options, for example, `NEAR/12` pattern search as a regexp operator, for example, `text:/bug.*/`
Tab	`\t`
Line feed	`\n`
Carriage return	`\r`
Round brackets	`( or )`
Square brackets	`[ or ]`
Curly brackets	`{ or }`
Colon	`:`
Equal sign	`=`
Greater than or less than	`< or >`
Comma	`,`

Note: % is not a reserved character.

Escaping UQL Operators Interpretation

You can add a backslash (\) to disable the interpretation of UQL operators (parentheses, =, {, }, etc.).

Note: If any tokenization takes place afterward, the tokenizer still decides how to enter the character. For example, \= is interpreted as a simple = but the default tokenization considers this character as punctuation. It is therefore removed from the query as any other punctuation character.
