I see at least two request parameters you are passing to the Spellchecker that may cause this :
<str name="spellcheck.onlyMorePopular">true</str> *The spellcheck.onlyMorePopular Parameter If true, Solr will to return suggestions that result in more hits for the query than the existing query. Note that this will return more popular suggestions even when the given query term is present in the index and considered "correct".* <str name="spellcheck.alternativeTermCount">2</str> *Specify the number of suggestions to return for each query term existing in the index and/or dictionary. Presumably, users will want fewer suggestions for words with docFrequency>0. Also setting this value turns "on" context-sensitive spell suggestions.* As a general suggestion, you may want to play with those parameters, as sometime you may need suggestions even if the term is in the index ( it can happen a mispelled term is in the index, but the corrected version is appearing much more frequently and deservers a better treatment). With Only More popular enabled you can play with thresholds of document frequencies with : maxQueryFrequency and thresholdTokenFrequency. *At first, spellchecker analyses incoming query words by looking up them in the index. Only query words, which are absent in index or too rare ones (below maxQueryFrequency ) are considered as misspelled and used for finding suggestions. Words which are frequent than maxQueryFrequency bypass spellchecker unchanged. After suggestions for every misspelled word are found they are filtered for enough frequency with thresholdTokenFrequency as boundary value. These parameters (maxQueryFrequency and thresholdTokenFrequency) can be a percentage (such as .01, or 1%) or an absolute value (such as 4). * N.B. this is taken from the Official Solr Wiki. We deeply encourage users to first read the documentation. ----- --------------- Alessandro Benedetti Search Consultant, R&D Software Engineer, Director Sease Ltd. - www.sease.io -- View this message in context: http://lucene.472066.n3.nabble.com/SolrSpellChecker-returning-suggestions-for-words-present-in-index-tp4334554p4334586.html Sent from the Solr - User mailing list archive at Nabble.com.
