exact form modified vs expanded keywords
Currently exact form modified = doesn't prevent expanding keywords, e.g.:
mysql> drop table if exists t;create table t(f text) min_infix_len='1' expand_keywords='1'; insert into t values(1,'abc'),(2,'bc');
mysql> select * from t where match('=bc');
------ ------
| id | f |
------ ------
| 2 | bc |
| 1 | abc |
------ ------
2 rows in set (0.00 sec)
mysql> show meta;
--------------- -------
| Variable_name | Value |
--------------- -------
| total | 2 |
| total_found | 2 |
| time | 0.002 |
| keyword[0] | *bc* |
| docs[0] | 2 |
| hits[0] | 2 |
| keyword[1] | bc |
| docs[1] | 1 |
| hits[1] | 1 |
--------------- -------
9 rows in set (0.00 sec)
It would be good to fix it.

also need to check wildcard modifiers, ie term? not get replaced by *term*
No news. This task is not in our nearest plans, but we'll be happy to review and accept a pull request.
@sanikolaev In fact we need to keep expand_keywords = 1, but have the ability to search by exact phrase.
@sanikolaev Hello! Half a year has passed :) Maybe you have any good news for me?
Hello @glukkkk
Sure, the good news are that:
- Manticore Columnar Library now supports RT indexes
- You can do ALTER to add/remove full-text field
- Secondary indexes are in progress
- Auto OPTIMIZE is almost done
- Manticore Helm chart and Prometheus exporter are ready
- Ukrainian lemmatizer has been implemented
All these tasks were of a higher priority for us since we believe it's more important for the community at the moment or someone wanted to sponsor development of some of these features, which allowed us to sustain the development in general. Unfortunately, this issue is of a lower priority and will be so until we are done with more important things or until someone makes a merge request. Thank you for your understanding.
