+\r
+That helped a lot! This is what I get:\r
+\r
+ $ notmuch count -- no NEAR \"plain\ text\"\r
+ Query string is:\r
+ no NEAR "plain text"\r
+ Exclude query is:\r
+ Xapian::Query()\r
+ Final query is:\r
+ Xapian::Query((Tmail AND Zno:(pos=1) AND near:(pos=2) AND Zplain:(pos=3) AND text:(pos=4)))\r
+ 465\r
+ $ notmuch count -- \"plain\ text\"\r
+ Query string is:\r
+ "plain text"\r
+ Exclude query is:\r
+ Xapian::Query()\r
+ Final query is:\r
+ Xapian::Query((Tmail AND (plain:(pos=1) PHRASE 2 text:(pos=2))))\r
+ 870\r
+\r
+I wanted the "plain text" to be treated as a phrase, as in the second\r
+case. I have tried nesting the quotes. The closest I got to was this:\r
+\r
+ $ notmuch count -- no NEAR 'plain\ text'\r
+ Query string is:\r
+ no NEAR plain\ text\r
+ Exclude query is:\r
+ Xapian::Query()\r
+ Final query is:\r
+ Xapian::Query((Tmail AND (no:(pos=1) NEAR 11 plain:(pos=2)) AND Ztext:(pos=3)))\r
+ 151\r
+\r
+I then tried this:\r
+\r
+ $ notmuch count -- no NEAR \(plain ADJ/1 text\)\r
+ Query string is:\r
+ no NEAR (plain ADJ/1 text)\r
+ Exclude query is:\r
+ Xapian::Query()\r
+ Final query is:\r
+ Xapian::Query((Tmail AND Zno:(pos=1) AND near:(pos=2) AND Zplain:(pos=3) AND (adj:(pos=4) PHRASE 2 1:(pos=5)) AND Ztext:(pos=6)))\r
+ 0\r
+\r
+Again, this is not what I was expecting. With the last one, I was\r
+expecting to group "plain" and "text" within a distance of 1, in the\r
+given order, and then requring "no" to be near (within 10 words, the\r
+default) the "plain ADJ/1 text" combination.\r
+\r
+Is my understanding of the query language completely wrong? Apart from\r
+`man notmuch-search-terms', I looked here:\r
+http://xapian.org/docs/queryparser.html\r
+\r
+Thanks for any help.\r
+\r
+Cheers,\r
