Hello, I have a function and a lot of documents, i want to select all documents that give a certain value when i pass a document's field through the function, i just want to filter by function, how?
I am thinking of implementing Collector. Get the docId, make a field look-up and discard if it doesn't pass my function. But i remember from quite some time ago, that doing field look-ups there would be expensive. Although i don't mind it taking some time (it is for batched work behind our scenes), do you have suggestions? Also, the last time i had to use a custom collector, i had to hack it into SolrIndexSearcher to use it. Is there any proper way to use a custom collector these days? Many thanks, Markus
