Solr Indexing & Searching -


could suggest me best way of using solr regular search products , should support synonyms & fuzzy search ?

suppose if search word cro, need products starting cro, cro occurrences anywhere in field, synonyms & fuzzy on in respective boosting

i have scenario project.

i using fuzzylookupfactory(with multiple suggester) , analyzinginfixlookupfactory. using solrj (java api) request query.

first search word analyzinginfixlookupfactory find word anywhere in field have input correctly. example product name "toshiba" if search "tosh" find "toshiba" correctly if search "toshba" not find product.

this time using fuzzylookupfactory suggester split words(for example have "toshiba laptop" word1=toshiba word2 = laptop etc.) , search 1 one , fuzzy find toshba -> toshiba , after find toshiba again use analyzinginfixlookupfactory find complete product field.

for example want find "toshiba laptop" , searched "toshba laptp". first try "analyzinginfixlookupfactory" , response null.after response null search fuzzy each word , add find toshba -> toshiba + laptp-> laptop toshiba laptop , can search again analyzinginfixlookupfactory complete field.

my analyzing suggester in (solrconfig.xml)
