Taking a look into the documentation I see this inconsistent orderings in my opinion :
*Example:* Concatenate word parts and number parts, but not word and number parts that occur in the same token. <analyzer> <tokenizer class="solr.WhitespaceTokenizerFactory"/> <filter class="solr.WordDelimiterFilterFactory" catenateWords="1" catenateNumbers="1"/> </analyzer> *In:* "hot-spot 100+42 XL40" *Tokenizer to Filter:* "hot-spot"(1), "100+42"(2), "XL40"(3) *Out:* "hot"(1), "spot"(2), "hotspot"(2) *(1?)*, "100"(3), "42"(4), "10042"(4) *(2?)*, "XL"(5)*(3?)*, "40"(6)*(4?)* *Example:* Concatenate all. Word and/or number parts are joined together. <analyzer> <tokenizer class="solr.WhitespaceTokenizerFactory"/> <filter class="solr.WordDelimiterFilterFactory" catenateAll="1"/> </analyzer> *In:* "XL-4000/ES" *Tokenizer to Filter:* "XL-4000/ES"(1) *Out:* "XL"(1), "4000"(2), "ES"(3), "XL4000ES"(3)*(1?)* I have not clear why a token generated by a catenation should not occupy the same position of the original one. In your example , I am a little bit surprised of the first results as well : "RRR-COLECCION: COLECCIÓN: Gracita Morales foobar Here are the final positions and terms that 4.7.2 yields for this on query analysis: 1 rrr-coleccion 1 rrr 2 coleccion 2 rrrcoleccion *(1) ?* 3 coleccion 4 gracita 5 morales 6 foobar It is not so clear, if the tokens must simply inherit their position from the "parent" token, or if they must arrange it based on the final list of tokens . 2015-07-08 16:03 GMT+01:00 Shawn Heisey <apa...@elyograg.org>: > On 7/8/2015 8:44 AM, Shawn Heisey wrote: > > This is what 4.9.1 does with it: > > > > 1 rrr-coleccion > > 2 rrr > > 2 coleccion > > 2 rrrcoleccion > > 3 coleccion > > 4 gracita > > 5 morales > > 6 foobar > > Followup: This is what Solr 5.2.1 does for query analysis, which also > seems wrong, and doesn't match the phrase query: > > 1 rrr-coleccion > 2 coleccion > 2 rrr > 2 rrrcoleccion > 3 coleccion > 4 gracita > 5 morales > 6 bleh > > The index analysis on 5.2.1 is the same as the other two versions. > > Thanks, > Shawn > > -- -------------------------- Benedetti Alessandro Visiting card : http://about.me/alessandro_benedetti "Tyger, tyger burning bright In the forests of the night, What immortal hand or eye Could frame thy fearful symmetry?"
