|

=item suggest |
| 42 |
|
| 43 |
Returns results for REST URIs like: |
| 44 |
|
| 45 |
C<search/suggest?search=FieldName&show=TitleProper&FieldName=query%20string> |
| 46 |
|
| 47 |
It will use C<search> field to filter results (and using additional |
| 48 |
C<FieldName> as value of search) and return C<TitleProper> field |
| 49 |
for results. |
| 50 |
|
| 51 |
If C<search> field has magic value <all>, it will search over all data, not |
| 52 |
just one specified field: |
| 53 |
|
| 54 |
C<search/suggest?search=all&show=TitleProper&all=query%20string> |
