Subject [jira] [Commented] (SOLR-3029) Poor json formatting of spelling collation info
Date Thu, 29 Mar 2012 02:13:27 GMT

Yonik Seeley commented on SOLR-3029:
------------------------------------

OK, this may be too much for 3.6.
I tried an example and it looks like there are a couple of places with this problem.

I edited solr.xml so the name field looked like
{code}
  <field name="name">Solr, the Enterprise Search Server solra solrb abcdefgx abcdefgy</field>
{code}

Then I tried the following spellcheck command:

http://localhost:8983/solr/spell?q=abcdefgq%20solrz&spellcheck=true&spellcheck.collate=true&spellcheck.build=true&spellcheck.collateExtendedResults=true&spellcheck.count=3&spellcheck.maxCollations=3&wt=json&indent=true

{code}
  "spellcheck":{
    "suggestions":[
      "abcdefgq",{
        "numFound":2,
        "startOffset":0,
        "endOffset":8,
        "suggestion":["abcdefgx",
          "abcdefgy"]},
      "solrz",{
        "numFound":3,
        "startOffset":9,
        "endOffset":14,
        "suggestion":["solra",
          "solrb",
          "solr"]},
      "collation",[
        "collationQuery","abcdefgx solra",
        "hits",0,
        "misspellingsAndCorrections",[
          "abcdefgq","abcdefgx",
          "solrz","solra"]]]}}
{code}

Apologies if I'm misinterpreting some things - I don't have much experience with the spellchecker
stuff (other than trying to clean up the tests in the past).
Observations:
- Unless order is really important, "suggestions" should be a map
- same for "collation" and "misspellingsAndCorrections"
- why is "collation" inside "suggestions" along with other words?  should this be one level
higher?
- why isn't this giving me multiple collations... am I misunderstanding the spellcheck.maxCollations
parameter
- why aren't multiple suggestions returned in misspellingsAndCorrections?  (and what's the
purpose of this seemingly redundant info anyway?)
- I briefly tried distributed search by adding &shards=localhost:8983/solr&shards.qt=/spell
and I get
{code}
  "error":{
    "msg":"isShard is only acceptable with search handlers",
    "code":400}}
{code}

> The correctlySpelled and collation key/values are stored as consecutive elements in an
array - quite odd. Is there a reason isn't not a key/value map like most things?
