How to search multiple value in rest service using finder method

Content

Hi,

Need some advise on the rest service using finder method

the syntax says, <finder>;<attr1>=<val1>,<attr2>=<val2>.

example: finder=MyOpportunitiesFinder;Name=Local,Country=UK

if I want to search "Name" with values 'Local' or 'External', how can I search?

I tried below but didn't seem working
finder=MyOpportunitiesFinder;Name='Local','External',,Country=UK
finder=MyOpportunitiesFinder;Name='Local' OR 'External',,Country=UK
finder=MyOpportunitiesFinder;Name=Local,Name=External,,Country=UK
finder=MyOpportunitiesFinder;Name=*,Country=UK

Thanks
Sreejit
