Search returning unexpected matches at the top

[rhys J]

I have a search box that is just searching every possible core, and every
possible field.

When I enter 'owl-2924-8', I expect the clt_ref_no of OWL-2924-8 to float
to the top, however it is the third result in my list.

Here is the code from the search:

on_data({
  "responseHeader":{
    "status":0,
    "QTime":31,
    "params":{
      "hl":"true",
      "indent":"on",
      "fl":"debt_id, clt_ref_no",
      "start":"0",
      "sort":"score desc, id asc",
      "rows":"500",
      "version":"2.2",
      "q":"clt_ref_no:owl\\-2924\\-8 debt_descr:owl\\-2924\\-8
comments:owl\\-2924\\-8 reference_no:owl\\-2924\\-8 ",
      "core":"debt",
      "json.wrf":"on_data",
      "urlquery":"owl-2924-8",
      "callback":"?",
      "wt":"json"}},
  "response":{"numFound":85675,"start":0,"docs":[
      {
        "clt_ref_no":"2924",
        "debt_id":"574574"},
      {
        "clt_ref_no":"2924",
        "debt_id":"598663"},
      {
        "clt_ref_no":"OWL-2924-8",
        "debt_id":"624401"},
      {
        "clt_ref_no":"OWL-2924-8",
        "debt_id":"628157"},
      {
        "clt_ref_no":"2924",
        "debt_id":"584807"},
      {
        "clt_ref_no":"U615-2924-8",
        "debt_id":"628310"},
      {
        "clt_ref_no":"OWL-2924-8/73847",
        "debt_id":"596713"},
      {
        "clt_ref_no":"OWL-2924-8/73847",
        "debt_id":"624401"},
      {
        "clt_ref_no":"OWL-2924-8/73847",
        "debt_id":"628157"},
      {

I'm not interested in having a specific search with quotes around it,
because this is searching everything, so it's a fuzzy search. But I am
interested in understanding why 'owl-2924-8' doesn't come out on top of the
search.

As you can see, I'm sorting by score and then id, which should take care of
things, but it's not.

Thanks,

Rhys
