Hi Trevor

I felt this is really great plugin when I tried free version. Now I purchased pro version, and I feel some important factors are different from free version and pro version.

For example, I like search slug of free version rather than pro version.

Because my webiste has code which enable to search custom meta(custom field) by the code in functions.php
Thus, free version of SF works fine because its search slug is same as normal search at my website.

However, pro version changes search slug to different one, and it stopped to search custom meta(custom field).

slug of free version
mydomein/?s=searchword

slug of pro version
mydomein/?sfid=00000&_sf_s=searchword

Now, what I like to know is how I can keep regular search slug like “mydomein/?s=searchword” on pro version instead of another slug made by pro version. If its difficult, then I need to change pro version to free version. Is there any way to exclude or restrict certain category at free version?

I tried plugin Relevanssi to search custom meta(custom field), but their annual cost is much higher than SF pro and require much extra work on search.php. Also Relevanssi said he is suitable for small website only.

I like to keep my function code for custom meta(custom field) search.
Is there any way to let SF pro search like my original search function? This is code on function.php that enable search through custom meta(custom field) as original search function.
