[Grok-dev] Assertion error when quering TextIndex

[Sebastian Ware]

Maybe I am making a silly mistake, but I am doing this...

from hurry.query.query import Query, Text

class ContentIndexes(grok.Indexes):
     grok.site(ProtonCMS)
     grok.context(interfaces.IProtonObject)
     grok.name('proton_catalog')

     text_body = index.Text(attribute='body')
     body = index.Field(attribute='body')

...and this works...

def search_content(self, search_term):
     result = Query().searchResults(
                      query.Eq(('proton_catalog', 'body'), search_term)
                      )
     return result

...but this gives a ComponentLookupError...

def search_content(self, search_term):
     result = Query().searchResults(
                      Text( ('', 'text_body'), search_term)
                      )
     return result

...the traceback...
