json - solr: facet search multivalued field containing the same value multiple times -


i have field in solr document (in json):

somefield = [value1, value2, value3, value4,...];

i want know how many documents there containing each of values.

the facet search executing works there 1 problem: values represent hierarchy (denoted sequence) , same value appear on different levels in hierarchy (representing different entity).

e.g.

(in document1) somefield = [value1, value2, value3, value4]; (in document2) somefield = [value1, value3, value4, value5]; (in document3) somefield = [value1, value3, value3, value4];

so result should looke this:

value1 = 3 value2 = 1 value3 = 2 (level 2) value3 = 2 (level 3) value4 = 1 (level 3) value4 = 2 (level 4) value5 = 1

on inserting documents, can see inserting

value1, value3, value3

is inserted correctly (solr doesn't convert value1, value3)

how can achieve faceting, i. e. make solr treat each level of somefiled separately , not count value3 1 field?

you can't. token token when comes faceting.

you can use secondary field , add metainformation tokens when indexing (from own code), contain level token on.

so example above, you'd have second field named somefield_indexed content:

[1_value1, 2_value2, 3_value3, 4_value4] [1_value1, 2_value3, 3_value4, 4_value5] [1_value1, 2_value3, 3_value3, 4_value4]

the resulting facet be:

1_value1: 3 2_value2: 1 2_value3: 2 3_value3: 2 3_value4: 1 4_value4: 2 4_value5: 1

remove , including first _ when you're displaying contents facets. it'll allow filter on location of value (i.e. display documents have value3 in second location, using fq=somefield_indexed:2_value3.

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj...

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer ...
