++In addition to individual terms, multiple terms can be combined with\r
++Boolean operators (**and**, **or**, **not**, and **xor**). Each term\r
++in the query will be implicitly connected by a logical AND if no\r
++explicit operator is provided, (except that terms with a common prefix\r
++will be implicitly combined with OR).  The shorthand '-<term>' can be used for 'not <term>' but\r
++unfortunately this does not work at the start of an expression.\r
+ Parentheses can also be used to control the combination of the Boolean\r
+ operators, but will have to be protected from interpretation by the\r
+ shell, (such as by putting quotation marks around any parenthesized\r
+ expression).\r
+ \r
++In addition to the standard boolean operators, Xapian provides several\r
++operators specific to text searching.\r

++::\r

++        notmuch search term1 NEAR term2\r

++will return results where term1 is within 10 words of term2. The\r
++threshold can be set like this:\r

++will return results where term1 is within 10 words of term2, but in the\r
++same order as in the query. The threshold can be set the same as with\r
