Yep, you are right!
And a BIG THANKS for solving this.
Without these ... -_- it DOES find them in Title Only Search
I will stop adding -_- and remove them from past pics.
Fortunately it does correctly find -PI#233849- in any other search mode using only PI#233849
As a coincidence, today I realized something at our vB forums on the same line...
Plant nomenclature rules - list plants as ... Genus species 'Cultivar'
example - Cucurbita maxima 'Atlantic'
Guess what I realized!!! A search for Atlantic without the '_' returns 0 finds in both search functions at vB, and alas, also at PP.
I guess it's time to throw away the nomenclature rule book!
