solr

问题 For a filter query in Solr, I need to include all documents not of a certain type, plus any documents of that type which have a value in a certain field. I tried this: fq=(-type_id:(A) OR content:(['' TO *])) But it is excluding documents of type_id B, C, etc. which have null content . ( type_id is a string field and content is text .) I have seen this question: Complex SOLR query including NOT and OR and this post about operators: http://robotlibrarian.billdueber.com/2011/12/solr-and-boolean

问题 I have a list of items as: i = SearchQuerySet().models(Item) now, each item in i has a attribute, price I want to narrow the result in which price information is not available along with the ones falling in a given range something like i.narrow('price:( None OR [300 TO 400 ] )') how can that be done? 回答1: Try this: -(-price:[300 TO 400] AND price:[* TO *]) is logically the same and it works in Solr. 回答2: As per the SolrQuerySyntax Pure Negative Queries: -field:[* TO *] finds all documents

问题 I'm working on a feature which relies on sorting the value of function query. Function query is as below : http://localhost:8983/solr/collection/select?q=*:*&sort=if(exists(f1_t), f1_t, theme)+ASC&wt=json&indent=true The sort function is " if(exists(f1_t), f1_t, theme) ASC " So basically what I'm doing is if the field " f1_t " (which is a dynamic field of type TextField) exists then the sorting is based on the value of the field else the sorting is based on the value of "theme" which is also
