I have a problem with solr suggested terms, when I search for a miss spelled phrase or word, for example "halogan balbs" (0 results found) I want a suggestion which will lead to results (eg "halogen bulbs").
I'm able to get a suggested phrase enabling spellcheck.collation and spellcheck.maxCollationTries = 0, but unfortunately the suggested phrase does not always generate results (eg. searching for "fence panel" (1 result) suggests "face paper" (0 results) According to documentation, in order to bypass the problem of 0 results on the collated query I can configure spellcheck.maxCollationTries > 0, but by doing so I noticed that the returned collation is always empty, even when the single suggested words collated would generate results. My question is, why is that happening and how can I avoid it? Following an example of query for "halogen balbs" that does not work as I'm expecting: http://localhost:8983/solr/master_Product_default/select?fq=(catalogId:%22ProductCatalog%22%20AND%20catalogVersion:%22Online%22)&q=((code_string:halogan^100.0))%20OR%20((code_string:balbs^100.0))%20OR%20((code_string:%22halogan%20balbs%22~10.0^100.0)%20OR%20(brand.search_text_mv:%22halogan%20balbs%22~10.0^300.0)%20OR%20(categoryName_text_en_mv:%22halogan%20balbs%22~10.0^700.0)%20OR%20(type.search_text_mv:%22halogan%20balbs%22~10.0^800.0)%20OR%20(name_text_en:%22halogan%20balbs%22~10.0^500.0))&rows=20&spellcheck.dictionary=default&spellcheck.q=halogan%20balbs&spellcheck=true&spellcheck.collate=true&spellcheck.extendedResults=true&spellcheck.collateExtendedResults=true&spellcheck.count=100&spellcheck.maxCollationTries=500 that query returns the following: "spellcheck":{ "suggestions":[ "halogan",{ "numFound":1, "startOffset":0, "endOffset":7, "origFreq":0, "suggestion":[{ "word":"halogen", "freq":84}]}, "balb",{ "numFound":1, "startOffset":8, "endOffset":13, "origFreq":0, "suggestion":[{ "word":"bulb", "freq":198}]}], "correctlySpelled":false, "collations":[]}} Note that halogen and bulb is returned as single suggestion but collations is empty, whilst if I run the query with "spellcheck.maxCollationTries=0" then I get "halogen bulb" as suggested collation query: "spellcheck":{ "suggestions":[ "halogan",{ "numFound":1, "startOffset":0, "endOffset":7, "origFreq":0, "suggestion":[{ "word":"halogen", "freq":84}]}, "balb",{ "numFound":1, "startOffset":8, "endOffset":13, "origFreq":0, "suggestion":[{ "word":"bulb", "freq":198}]}], "correctlySpelled":false, "collations":[ "collation",{ "collationQuery":"halogen bulb", "hits":0, "misspellingsAndCorrections":[ "halogan","halogen", "balb","bulb"]}]}} I would expect this behaviour to happen if searching for "halogen bulb" returns 0 results, but in this particular case the search returns results: http://localhost:8983/solr/master_Product_default/select?fq=(catalogId:%22ProductCatalog%22%20AND%20catalogVersion:%22Online%22)&q=((code_string:halogen^100.0))%20OR%20((code_string:bulb^100.0))%20OR%20((code_string:%22halogen%20bulb%22~10.0^100.0)%20OR%20(brand.search_text_mv:%22halogen%20bulb%22~10.0^300.0)%20OR%20(categoryName_text_en_mv:%22halogen%20bulb%22~10.0^700.0)%20OR%20(type.search_text_mv:%22halogen%20bulb%22~10.0^800.0)%20OR%20(name_text_en:%22halogen%20bulb%22~10.0^500.0))&rows=20&spellcheck.dictionary=default&spellcheck.q=halogen%20bulb&spellcheck=true&spellcheck.collate=true&spellcheck.extendedResults=true&spellcheck.collateExtendedResults=true&spellcheck.count=100&spellcheck.maxCollationTries=500 returns: "response":{"numFound":42,"start":0,"docs":[ {...} -- Sent from: http://lucene.472066.n3.nabble.com/Solr-User-f472068.html
