solr

问题 I am new to solr, and I am facing a problem when I try to serialize/deserialize a Map in Solr. I use Spring Data Solr in my Java application as follow: @Field("mapped_*") private Map<String, String> values; It flatten and serializes my map in Solr as follow: "key1" : "value1" "key2" : "value2" ... However, when I run a search, the returned objects have this field always set as NULL. Deserialization does not work on this particular field, it looks like it does not recognize the key1, key2...

问题 I am writing a custom filter in Solr to post a token to Apache Stanbol for enhancement and index the response to a different field in the same document. In my test code below I have got the Stanbol response and have added it as a new document to Solr. My requirement is to add the stanbolResponse as a field value to the same document being indexed.

问题 I'm choosing between Solr and Sphinx. Sphinx doc page has a section called "5.3. Extended query syntax" which describes the following search parameters (among others) : strict order operator (example: aaa << bbb << ccc) - NEAR, generalized proximity operator (example: hello NEAR/3 world NEAR/4 "my test") - search according to distance between words SENTENCE/PARAGRAPH (example: "Bill Gates" PARAGRAPH "Steve Jobs") - search inside a sentence/paragraph Does Solr have any similar functionality?
