  Operators

+
+       In addition to individual terms, multiple terms can  be  combined  with
+       Boolean  operators (and, or, not, and xor). Each term in the query will
+       be implicitly connected by a logical AND if  no  explicit  operator  is
+       provided  (except  that  terms  with a common prefix will be implicitly
+       combined with OR).  The  shorthand  '-<term>'  can  be  used  for  'not
+       <term>' but unfortunately this does not work at the start of an expres‐
+       sion.  Parentheses can also be used to control the combination  of  the
+       Boolean operators, but will have to be protected from interpretation by
+       the shell, (such as by putting quotation marks around any parenthesized
        expression).
+
+       In  addition to the standard boolean operators, Xapian provides several
+       operators specific to text searching.
+
+          notmuch search term1 NEAR term2
+
+       will return results where term1  is  within  10  words  of  term2.  The
+       threshold can be set like this:
+
+          notmuch search term1 NEAR/2 term2
+
+       The search
+
+          notmuch search term1 ADJ term2
+
+       will return results where term1 is within 10 words of term2, but in the
+       same order as in the query. The threshold can be set the same  as  with
+       NEAR:
+
+          notmuch search term1 ADJ/7 term2
+
+ +

  Stemming

+
+       Stemming in notmuch means that these searches
+
+          notmuch search detailed
+          notmuch search details
+          notmuch search detail
+
+       will  all  return identical results, because Xapian first "reduces" the
+       term to the common stem (here 'detail') and then performs the search.
+
+       There are two ways to turn this off: a search for  a  capitalized  word
+       will  be performed unstemmed, so that one can search for "John" and not
+       get results for "Johnson"; phrase  searches  are  also  unstemmed  (see
+       below  for details).  Stemming is currently only supported for English.
+       Searches for words in other languages will be performed unstemmed.
+
+ +

  Wildcards

+
+       It is possible to use a trailing  '*'  as  a  wildcard.  A  search  for
+       'wildc*' will match 'wildcard', 'wildcat', etc.
+
+ +

  Boolean and Probabilistic Prefixes

+
+       Xapian  (and  hence  notmuch)  prefixes  are either boolean, supporting
+       exact matches like "tag:inbox"  or  probabilistic,  supporting  a  more
+       flexible term based searching. The prefixes currently supported by not‐
+       much are as follows.
+
+              ┌───────────────────────────┬────────────────────────────┐
+              │Boolean
+              ├───────────────────────────┼────────────────────────────┤
+              │
+              │
+              │       thread:     folder: │        subject:    attach‐ │
+              │       path:               │        ment: mimetype:     │
+              └───────────────────────────┴────────────────────────────┘
+

  Terms and phrases

+
+       In general Xapian distinguishes between lists  of  terms  and  phrases.
+       Phrases are indicated by double quotes (but beware you probably need to
+       protect those from your shell) and insist that  those  unstemmed  words
+       occur  in  that  order. One useful, but initially surprising feature is
+       that the following are equivalant ways to write the same phrase.
+
+       · "a list of words"
+
+       · a-list-of-words
+
+       · a/list/of/words
+
+       · a.list.of.words
+
+       Both parenthesised lists of terms and quoted phrases are ok with proba‐
+       bilisitic prefixes such as to:, from:, and subject:. In particular
+
+          subject:(pizza free)
+
+       is equivalent to
+
+          subject:pizza and subject:free
+
+       Both of these will match a subject "Free Delicious Pizza" while
+
+          subject:"pizza free"
+
+       will not.
