If a document cannot be indexed, it also cannot be searched. For example, documents that contain binary content cannot be indexed.

Only certain characters can be searched, such as alphabetic, numeric, extender, and custom characters. Custom characters include Chinese, Japanese, Korean letters, and months.

Other characters, including punctuation, accent, and diacritical marks, and characters such as | and #, are not indexed or searched. These characters are removed from the indexed text and are treated as blank spaces. The xPlore federation treats characters such as !@#$%^_,.&;:()+=< as white space.

The plus and minus signs cannot be used as operators. You must use the AND operator, and the OR instead.

The asterisk, and the question mark can be used as wildcards.
