How do I get solr term frequency? - lucene

I have a question that how could somebody get term frequency as we do get in lucene by the following method
DocFreq(new Term("Field", "value")); using solr/solrnet.

Try debugQuery=on or TermsComponent. None of them are currently supported through SolrNet, so you can either work around it, or implement them and contribute them to the project.

Geo.Lua function GEOMETRYFILTER and Redis

I'm trying to figure out how to actually do a call to GEOMETRYFILTER function in geo.lua since documentation is not very clear to me:
https://github.com/RedisLabs/geo.lua#GEOMETRYFILTER
What exactly do these parameters means and how do I call this function from Redis-cli? I was not able to find any example on google.
geo.lua's author here - IIRC it involves first creating a polyhash to describe the filter and then providing it along with the geoset to the library. Performance is quite horrible as everything is done in Lua.
FYI - that library is no longer maintained.

Using Field.index from apache lucene index

I am attempting to implement a simple lucene index, using Lucene 7.1.
There are allot of changes to the code between versions, so I am meeting a lot of changes from answer to answer.
In this tutorial I am following
https://www.avajava.com/tutorials/lessons/how-do-i-use-lucene-to-index-and-search-text-files.html
There is a line
document.add(new Field(FIELD_PATH, path, Field.Store.YES, Field.Index.UN_TOKENIZED));
However Field.Index is throwing up errors. I can convert it to TextField but I am not sure if this is the same thing. Can anyone tell me what Field.Index does and how one could modify the code so that it will run ?
That tutorial is using 2.3, it's so old the folks at apache don't even keep that version of lucene in the archives. It wouldn't bother with a resource that old, more headache than it's worth. Looks like they're mostly just going through the lucene demo that comes with every released version of lucene, though. Try going through the current Lucene demo, instead.
As far as what to replace that exact field with, it's indexed, stored and not tokenized, so you'll want to use a StringField. A TextField would be for a field that is tokenized.

custom error pages for IBM Domino iNotes

we're currently customizing iNotes for a customer (platform currently is Domino 9). We almost reached our goals, but one thing that's on our todo list I can't really figure out: they want us to also customize any possible error pages; see the following example screenshot:
This and other similar pages seem to come from the central Forms9.nsf which I'd love to leave as it is. We so far tried domcfg.nsf mappings, but as this is an iNotes internal error it obviously can't work; I also tried to figure out a way to put seomething into our customized Forms9_x.nsf but without any hint this is too abstract for me.
So my questions are:
has anyone ever done this?
what options do we have (apart from "hacking" Forms9.nsf)?
Many thanks in advance...
Update:
After continuing to play with domcfg mappings I suddenly saw a first result; not sure what's the difference to the first attempts, though; maybe moving the error form to Forms9_x.nsf did the trick? I'll keep investigating and post an answer if I can find one...
Alright, this has been an afternoon of wild guessing and hacking along, but finally I think I found it:
first of all, my playing around with domcfg mappings didn't have to do with solving the problem; instead, I just by chance had put my error page form into my Forms9_x.nsf and named it $$ReturnGeneralError (that's simply the name used in Forms9.nsf...; I completely had forgotton about those 4 pre-defined form names back from Domino 5 times).
What did not work was the old method of simply including a text file named MessageString to display the exact error message returned from the server; obviously iNotes is handling those error strings differently.
After a few hours of testing, and comparing codes between the standard iNotes error page and mine I finally found it: include some iNotes specific computed text into the page, in my case that is
#{{MessageString}; html}
See this document for some details (last row in the table)
Hopefully this can help someone else as well...

Is there any good tutoria or reference for writing code with Magma?

Currently I am trying to use Magma to do matrix operation on GPU, however, I found few documents about it. The only thing I can refer to is its testing program and the online generated document(here), which is not convenient to use. And the user guide seems outdated.
If you look here, getri and potri are supported.

Lucene 3.6.0 - SnowballAnalyzer Stemmer Deprecated

today I was trying to use the SnowballAnalyzer on Lucene Java API v3.6.0 but it seems Deprecated already. When I try to use the analyzer on my code, the code stop when it reach the analyzer. Actually I want to use PorterStemmer but it was not available on luce, so I decided to use this snowball, but this problem occured.
Anyone knows how to fix this?
Plus, does anyone know how to set the stop word file format, cause when I put:
a
as
able
about
above
according
accordingly
across
actually
after
afterwards
.
.
.
In the stopword.txt, and call it, the program stop. Can anyone share with me how to format the stopword.txt file?
Thanks.
being deprecated cannot make your code stop running. You must have some other issue.
Your stopword.txt seems to have the right format.
