In this video, learn how to build a search expression dynamically based on the parameters provided by the client.
- [Instructor] In order to use the search terms…from the client in our database queries,…we need to implement the apply method…in the search options class.…Typically, you'd use the link where method…to add a search term to a database query.…So, we might say something like…where name equals Oxford Suite.…This only works, however, if you know the search terms…at compile time.…In our case, we need to dynamically…build the link expression depending on the parameters…in the incoming request.…To keep the search options class light,…we'll delegate this responsibility…to the search options processor, as well.…
Create a new search options processor…for this resource and entity type.…Pass in the parameters, and then just return…processor.Apply, passing in the query.…So, now we have to go implement the apply method…on the search options processor.…This method will return an IQueryable of TEntity,…and it will accept an IQueryable of TEntity.…As we discussed when we were building…the sort options processor, it's important to use…
