TermsComponent - AutoComplete - Multiple Term Suggestions Inclusive Search?
Hi, I'm using the Terms Component to se up the autocomplete feature based on a String field. Here are the params I'm using: terms=trueterms.fl=typeterms.lower=catterms.prefix=catterms.lower.incl=false With the above params, I've been able to get suggestions for terms that start with the specified prefix. I'm wondering wether it's possible to: - have inclusive search, i.e., by typing cat, we get category, subcategory, etc.? - start suggestion from any word in the field. i.e., by typing cat, we get The best category...? Thanks! -Saïd
Re: TermsComponent - AutoComplete - Multiple Term Suggestions Inclusive Search?
Hi Saïd, I think your problem is the field's type: String. You have to use a TextField and apply tokenizers that will find subcategory if you put in cat. (Not sure which filter does that, though. I wouldn't think that the PorterStemmer cuts off prefix syllables of that kind?) If, however, you search on an analyzed version of the field it should return hits as usual according to the analyzer chain, and you can thus use the values of that field listed in the hits as suggestions. Exmple: input: potter field type: solr.TextField (with porter stemmer) finds: Harry Potter and Whatever and also Potters and Plums Cheers, Chantal On Wed, 2010-06-23 at 13:17 +0200, Saïd Radhouani wrote: Hi, I'm using the Terms Component to se up the autocomplete feature based on a String field.

To build your autocompletion, you can use the NGramFilterFactory. If you type cat It will match subcategory and the best category. If you change your mind and you don't want anymore to match subcategory, you can use the EdgeNGramFilterFactory. -- View this message in context: http://lucene.472066.n3.nabble.com/TermsComponent-AutoComplete-Multiple-Term-Suggestions-Inclusive-Search-tp916530p916769.html Sent from the Solr - User mailing list archive at Nabble.com.
