Hi,

Since BZ 30055 search is using the REST API.

For a library with 80,000 borrowers and  800,000 borrower_attributes, (one
searchable per borrower), searching a borrower is twice as slow and is
noticeable in checkin/checkout.

before 30055 the request was something like :
SELECT borrowernumber FROM borrowers 
WHERE firstname` LIKE '%foo%' 
OR middle_name LIKE '%foo%' 
OR surname LIKE '%foo%' 
OR othernames LIKE '%foo%' 
OR cardnumber LIKE '%foo%' 
OR userid LIKE '%foo%'
OR borrowernumber in ( 
  select borrowernumber from borrower_attributes where attribute LIKE '%foo%'
AND code = 'BAR' ) 
GROUP BY borrowernumber;
runtime 0.069 sec

in master
SELECT borrowernumber FROM borrowers 
LEFT JOIN borrower_attributes USING(borrowernumber) 
WHERE firstname` LIKE '%foo%' 
OR middle_name LIKE '%foo%' 
OR surname LIKE '%foo%' 
OR othernames LIKE '%foo%' 
OR cardnumber LIKE '%foo%' 
OR userid LIKE '%foo%'
OR (attribute LIKE '%foo%' AND code = 'BAR' ) 
GROUP BY borrowernumber;

runtime 1.324 sec
