NRediSearch create index on hash prefix

[rakhimzhanov]

Hi team,

Is there any way to create an index with prefix in the library NRediSearch like below?
FT.CREATE idx:movie ON hash PREFIX 1 "movie:" SCHEMA title TEXT SORTABLE release_year

Example was used from this source

I am having this exact question. I store objects of multiple classes so to say, and I need this "prefix" thing for Redisearch to work as expected.

the PREFIX API is exposed in the NuGet version 2.2.11, via the IndexDefinition type

I read this thread and also found it out, thank you!

But how can I specify prefixes when adding documents?

A object of the IndexDefinition type can only go to ConfiguredIndexOptions, which will then be supplied only to CreateIndex() or its async counterpart. Not to AddDocument()

When you add a document you also need to specify the prefix so I think we need the ConfiguredIndexOptions as one of the parameters here too

If you are using AddDocumentAsync for example you can specify the docId parameter with the prefix, for example: movie:11002
