Hi,
I have some issues with stemming on spell corrections and auto completes.
Given below is a sample record from my docs.
<doc>
<field name="id">K-82</field>
<field name="GrantNumber">22570</field>
<field name="GrantTitle">Extension IPM Coordination Program</field>
<field name="FundingSponsor">US Department of Agriculture</field>
<field name="DateAwarded">2009-06-11T00:00:00Z</field>
<field name="AwardTotal">1800000</field>
<field name="ProgramName">Extension Integrated Management Coordination
Program</field>
<field name="DepartmentName">Agronomy</field>
<field name="DepartmentName">Entomology</field>
<field name="DepartmentName">Plant Pathology</field>
<field name="CollegeName">Agriculture</field>
<field name="CollegeName">Cooperative Extension</field>
<field name="InvestigatorName"> Phillips, Marcelo</field>
<field name="InvestigatorName"> Kennelly, James</field>
<field name="InvestigatorName"> Michaud, Alberto</field>
</doc>
This is the schema.xml

<searchComponent name="spellcheck" class="solr.SpellCheckComponent">

<lst name="spellchecker">

1) spelling issue
If I submit the following URL to get the spelling suggetions for
'humanites', I get 'human' instead of 'humanities'.
http://localhost:8983/solr/spell/?q=humanites&spellcheck=true&spellcheck.collate=true
It seems like if I change the type of 'fSpell' to 'string' the query would
not work. Any suggestions?
2) Auto complete issue
Currently I'm using the following URL for auto complete.
http://lib-dev-web1.lib.campus:8983/solr/terms?terms.fl=fSpell&terms.sort=index&terms.prefix=huma&indent=true&wt=php&omitHeader=true
Then I get 'human' as the only suggestion, but I would rather get
few suggestions like 'humanities', 'human ecology'.
I also tried the following URL.
http://lib-dev-web1.lib.campus:8983/solr/select/?incident=on&qt=dismax&facet=on&rows=0&facet.limit=10&facet.mincount=1&facet.field=GrantTitle&q=kansas&facet.prefix=st
For the auto complete I would like to be able to create a field with
Investigator names, Grant titles, Program names, department names, etc ..
and to match strings off that. For example if I type 'hum' get
some suggestions as given below.
- Hummer, David (a name)
- Evaluation of Live Attenuated B. Melitensis Vaccines in Non-Human Primates
(a grant title)
- Program of global humanities (a program name)
- Humanities and Cultural bonding (a program name)
- Department of Human Nutrition (a department name)
- College of Human Ecology (a college name)
- Human-Robot Teams Informed By Human Performance Moderator Functions (a
grant title)
Any ideas on how to achieve this?
Thanks,
Dhanushka.
