hi
imagine i have a folder contain a meta data ; for example a field with value of name=Alex
under this folder i have many filed each have a different metadata; for example a file with metadata filed doctype=picture

i want to search doctype=picture under a folder that its metadata filed name=Alex
how can i do that? or in simple i want to search a document by metadata under a folder that has a specific metadata value.

thank you

Hierarchical searches will have always poor performance. Possible scenarios:
1- In case single hierarchy ( parent-child ) could use search based in SQL. I think should get a good performance, but only will working with a single level.
2- In case several levels in the hierarchy ( also in simple case can use ), you could propagate parent metadata to the child. Then in the child node, you have all the data to apply the filter. About how to apply automatically you could use an Automation task for it purpose ( I can guide on how to build it if it is your direction ).
