Lucene Analyzer chain: ShingleFilter without filler tokens

由 放肆的年华 提交于 2019-12-10 17:56:54
问题 In my analyzer chain, ShingleFilter comes after stopword filter. As mentioned in the docs, ShingleFilter handles position increments > 1 by inserting filler tokens (tokens with termtext "_"). For example : "please divide this sentence into biword shingles" Shingles of size 2 : please divide, divide _, _ sentence, sentence _, _ biword, biword shingles (assuming that "this, "into" are stopwords) I would like to eliminate those shingles with the filler tokens, i.e. my desired output contains

What differs between post-filter and global aggregation for faceted search?

由 回眸只為那壹抹淺笑 提交于 2019-12-09 13:21:15
问题 A common problem in search interfaces is that you want to return a selection of results, but might want to return information about all documents. (e.g. I want to see all red shirts, but want to know what other colors are available). This is sometimes referred to as "faceted results", or "faceted navigation". the example from the Elasticsearch reference is quite clear in explaining why / how, so I've used this as a base for this question. Summary / Question: It looks like I can use both a

ArangoDB Faceted Search Performance

由 纵然是瞬间 提交于 2019-12-08 19:36:31
问题 We are evaluating ArangoDB performance in space of facets calculations. There are number of other products capable of doing the same, either via special API or query language: MarkLogic Facets ElasticSearch Aggregations Solr Faceting etc We understand, there is no special API in Arango to calculate factes explicitly. But in reality, it is not needed, thanks for a comprehensive AQL it can be easily achieved via simple query, like: FOR a in Asset COLLECT attr = a.attribute1 INTO g RETURN {

Django Haystack Faceting examples

由 百般思念 提交于 2019-12-07 21:26:45
问题 I want to use Django-Haystack-Solr in a site I am working on. I have worked through the examples in the Haystack documentation and have searched the internet extensively for other examples. I am having difficulty making the leap to integrating it in my site. I found http://www.slideshare.net/Nagyman/faceted-navigation-using-django-haystack-and-solr interesting, but fell short of how to pull it all together. If anyone has run across some "robust" Haystack faceting examples, websites that are

Faceting using SolrJ and Solr4

由 走远了吗. 提交于 2019-12-07 06:32:09
问题 I've gone through the related questions on this site but haven't found a relevant solution. When querying my Solr4 index using an HTTP request of the form &facet=true&facet.field=country The response contains all the different countries along with counts per country. How can I get this information using SolrJ? I have tried the following but it only returns total counts across all countries, not per country: solrQuery.setFacet(true); solrQuery.addFacetField("country"); The following does seem

Extracting Distance from FacetWP Proximity Function to Display in Wordpress Template

I am quite new to Wordpress & Php coding in general, I have a relatively simple theme that I have been working with that contains a custom post type that stores latitude and longitude. Each post is a listing a hotel listing within a directory. The theme I am using also integrates with FacetWP the faceting plugin for WordPress. It is possible for the user to search the site by typing a location of locating themselves, this happens using Googles Mapping functionality. When the search is submitted parameters are passed to an archive page: http://localhost:8888/wowgoddess/listings/?fwp_location=43
