Search API View, search relation fields I am creating a search api view based on Search API (with Database backend for now (will change to solr later)).

I have 2 entities that are being indexed i.e. project and client.

A project contains a projectnumber and an entity reference to a client. The client contains a firstname and lastname.

I have added a view that shows the projectnumbers and (via relation to client entity) the first and lastname.

I want my exposed fulltext search to search these 3 fields (projectnumber, firstname and lastname).

The weird thing is that he only seems to search on projectnumber and not the first and lastname.

Does anybody have a workaround/solution for this?

Thanks in advance!
There's 2 areas you need to check this is included.  It's common to have applied to the search and not realise it needs to applied in views also. 

I take it so far you have made the fields in 

configuration > search api > Operations 'EDIT'   

"Fields" tab > 'Add Related Fields ' at the bottom. 

Now you also need to add the Fields in 

structure > views > your view 

Filter Criteria >  

On the right hand side look for 'Searched Fields'  - make sure all the fields your searching are in here.  

I hope that solves it for you .
