Hi there,
I am an expert bughunter for Joomla CMS websites.
It shows there are about 250 issues resolved in 3.4.4 and a few of them could have impacted your custom search module, especially if the builder overridden some standard functions from the Joomla core. What version of Joomla was the search still working as expected?
Finding and solving the issue can be anything from 1 hour. I will invoice a maximum of 20 hours even if it will take longer to find. If less than 20 hours, only that time will be invoiced.
Let me know if I can do this for you.
Best regards,
Marty
