55 |
C<$search> is an arrayref where each element is a hashref containing |
56 |
a part of the search. |
57 |
|
58 |
The hashref must contain a 'term', which is the string, and may contain other |
59 |
things to adjust how the search is performed: |
60 |
|
61 |
=over 4 |
62 |
|
63 |
=item field |
64 |
|
65 |
the field to search on, as defined in the C<search_field> table. If |
66 |
unspecified, all fields will be searched over. |
67 |
|
68 |
=item exact |
69 |
|
70 |
do an exact, literal, phrase match rather than a tokenised search. This will |
71 |
also ignore things like truncation and fuzziness. |
72 |
|
73 |
=back |
74 |
|
75 |
The C<%options> may be: |
76 |
|
77 |
=over 4 |
78 |
|
79 |
=item and_or |
80 |
|
81 |
either "and" or "or", and determines how multiple terms are combined. Default |
82 |
is "and." |
83 |
|
84 |
=back |
85 |
|
86 |
=head3 Returns |
87 |
|
88 |
a query structure intended to be passed to elasticsearch. |
89 |
|
90 |
=head3 Note |
91 |
|
92 |
This is pretty limited, it's intended that more options be added as necessary |
93 |
to support new functionality. |
94 |
|
95 |
=head3 Note 2 |
96 |
|
97 |
This ultimately ought to be replaced with a query parser driver, but that code |
98 |
is not documented so it'll take a while to figure out. |
