/* Create a new query for 'database'.
*
* Here, 'database' should be an open database, (see
* notmuch_database_open and notmuch_database_create).
*
* For the query string, we'll document the syntax here more
* completely in the future, but it's likely to be a specialized
* version of the general Xapian query syntax:
*
* http://xapian.org/docs/queryparser.html
*
* As a special case, passing either a length-zero string, (that is ""),
* or a string consisting of a single asterisk (that is "*"), will
* result in a query that returns all messages in the database.
*
* See notmuch_query_set_sort for controlling the order of results.
* See notmuch_query_search_messages and notmuch_query_search_threads
* to actually execute the query.
*
* User should call notmuch_query_destroy when finished with this
* query.
*
* Will return NULL if insufficient memory is available.
