Document search on partial words

阅读更多关于 Document search on partial words

问题 I am looking for a document search engine (like Xapian, Whoosh, Lucene, Solr, Sphinx or others) which is capable of searching partial terms. For example when searching for the term "brit" the search engine should return documents containing either "britney" or "britain" or in general any document containing a word matching r *brit* Tangentially, I noticed most engines use TF-IDF (Term frequency-Inverse document frequency) or its derivatives which are based on full terms and not partial terms.

阅读更多关于 Count total search objects count in template using django-haystack

问题 I am using django haystack with xapian as the backend search engine. I am using FacetedSearchView and FacetedSearchForm for faceting over the search. I have passed searchqueryset to the FacetSearchView in my urls.py file. But the problem is I cannot access that searchqueryset in template. All I want to do is count the number of objects in searchqueryset found. In shell I could achieve it using S earchQuerySet().filter(content="foo").count() , how can I do that similarly in the template?
