The borrowers search is by default on columns surname, firstname,
othernames and cardnumber.
(See C4::Members::_express_member_find).
Adding DB indexes will really increase the query speed.
This patch adds DB indexes on surname, firstname, othernames (cardnumber
has already an index).
Those indexes must be defined with a size because columns are mediumtext.
Test plan :
Test with mysql client :
mysql> explain select * from borrowers where surname like 'A%';
+----+-------------+-----------+-------+---------------+-------------+---------+------+------+-------------+
| id | select_type | table | type | possible_keys | key | key_len | ref | rows | Extra |
+----+-------------+-----------+-------+---------------+-------------+---------+------+------+-------------+
| 1 | SIMPLE | borrowers | range | surname_idx | surname_idx | 767 | NULL | 395 | Using where |
+----+-------------+-----------+-------+---------------+-------------+---------+------+------+-------------+
=> key show the index is used

Works as described, changes from updatedatabase and in kohastructure match.
I think deletedborrowers can be left out, as it's not queried when doing
patron searches. Patron deletes still work as expected.
