I have problem with .sort()
method. For example I have Index with Text() field:
FILTER = token_filter(
'FILTER', 'edge_ngram', min_gram=3, max_gram=40)
ANALYZER = analyzer(
'ANALYZER', tokenizer='standard', type='custom', filter=[
'standard', 'lowercase', 'stop', 'asciifolding',FILTER])
class Article(DocType):
title = Text(analyzer=ANALYZER)
body = Text(analyzer='snowball')
tags = Keyword()
search = Article.search().sort('title')
search.execute()
when I try to execute search query with sort I get an error:
elasticsearch.exceptions.RequestError: TransportError(400, 'search_phase_execution_exception', 'Fielddata is disabled on text fields by default. Set fielddata=true on [title] in order to load fielddata in memory by uninverting the inverted index. Note that this can however use significant memory.')
How can I sort by title
field properly in this case without setting fieldata=true
?
