"Subject" Fields: Populations and Purposes
This is Naomi Dushay's best attempt to understand the “subject” fields in VuFind as of 2008-08-11. It is not guaranteed to be correct, nor up to date. It is shared here in the hopes it may be useful to others.
Topic Fields
| Field Name | Function | Traits | Current Algorithm |
|---|---|---|---|
| topic | Search: Topic Fielded Search (boost: 50) default (two flavors of use, boosted 750, 30) | tokenized, stopwords, stemmed, case folded multivalued stored (should it be?) | 600a + 600b + 600c + 600d 600p, 600q, 600t 610a + 610b 610p, 610t 630a, 630p, 630s, 630t 650a |
| topicStr | Facet (search results) Subject Fielded Search (boost: 500) Item View - subject links have hidden search term for each existing 600, 610, 630, 650 Author View - get subjects by author | not tokenized multivalued not stored | same as topic field |
| fulltopic | Search: Topic Fielded Search (boost: 1) Subject Fielded Search (three flavors - boosted 300, 100, 1) getMoreLikeThis (two flavors - boosted 300, 250) | tokenized, stopwords, stemmed, case folded multivalued \\stored (should it be?) | 600 all subfields 610 all subfields 630 all subfields 650 all subfields |
| subtopic | Item View - subject links have hidden search term for each existing 600, 610, 630, 650 v,x,y,z | tokenized, stopwords, stemmed, case folded multivalued stored (should it be?) | 600v, 600x, 600y, 600z 610v, 610x, 610y, 610z 630v, 630x, 630y, 630z 650v, 650x, 650y, 650z |
Geographic Location Fields
| Field Name | Function | Traits | Current Algorithm |
|---|---|---|---|
| geographic | Search: default (two flavors of use, boosted 300, 30) Geo Fielded Search (boost: 50) | tokenized, stopwords, stemmed, case folded multivalued stored (should it be?) | 651a |
| geographicStr | Facet (search results) Subject Fielded Search (boost: 500) Item View - subject links have hidden search term for each existing 651a Browse View - browse by Region | not tokenized multivalued not stored | same as geographic field |
| fullgeographic | Search: Subject Fielded Search (three flavors - boosted 300, 100, 1) Geo Fielded Search (boost: 1) | tokenized, stopwords, stemmed, case folded multivalued stored (should it be?) | 651 all subfields |
| subgeographic | Item View - subject links have hidden search term for each existing 651 v,x,y,z | tokenized, stopwords, stemmed, case folded multivalued stored (should it be?) | 651v, 651x, 651y, 651z |
Genre Fields
| Field Name | Function | Traits | Current Algorithm |
|---|---|---|---|
| genre | Search: default (two flavors of use, boosted 300, 30) Genre Fielded (boost: 50) | tokenized, stopwords, stemmed, case folded multivalued stored (should it be?) | 655a, 655b |
| genreStr | Facet (search results) Subject Fielded Search (boost: 500) Item View - subject links have hidden search term for each existing 655a Browse View - browse by genre | not tokenized multivalued not stored | same as genre field |
| fullgenre | Search: Subject Fielded (three flavors - boosted 300, 100, 1) Genre Fielded (boost: 1) | tokenized, stopwords, stemmed, case folded multivalued stored (should it be?) | 655 all subfields |
| subgenre | Item View - subject links have hidden search term for existing 655v, 655x, 655y, 655z | tokenized, stopwords, stemmed, case folded multivalued stored (should it be?) | 655v, 655x, 655y, 655z |
Era Field
| Field Name | Function | Traits | Current Algorithm |
|---|---|---|---|
| era | Facet (search results) Search: Subject Fielded (three flavors, boost: 300, 100, 1) Era Fielded (only field) Browse view - browse by era | not tokenized multivalued stored (should it be?) | 650y, 651y |
