I don't like the BLF search feature at all :D
These days I rather do the following.. Go to google and type this: site:budgetlightforum.com _empty space_ "search query".
so something like this: site:budgetlightforum.com how to review
And it works even better when you add a nickname that you remember from the thread.
In the past I had been looking for this thread many times: https://budgetlightforum.com/t/-/20189
But when I use the search feature in BLF I almost never found it, so I changed the title a bit in order to find it better, but still would not be able to find if I forgot what the exact phrase was... If you use the above mentioned Google way, you can much easier find the thread you were looking for! I mean.. MUCH better.
