Proper snowball analyzer configuration when using Grails Searchable Plugin
- by Wirsbro
To improve stemming we want to switch from the default analyzer to snowball, however, having a lot of difficulty with the proper settings and would appreciate any help. In
Environment:
- Sun's Java 1.6.16
- Grails 1.2.2
- Searchable Plug-In 0.5.5
Config.groovy:
Have tried both settings:
compassSettings = ['compass.engine.analyzer.stemmed.type': 'snowball',
'compass.engine.analyzer.stemmed.name': 'English']
compassSettings = ['compass.engine.analyzer.snowball.type': 'snowball',
'compass.engine.analyzer.snowball.name': 'English',
'compass.engine.analyzer.search.type': 'snowball',
'compass.engine.analyzer.search.name': 'English']
Search.groovy - The Invocation:
def searchResult = searchableService.search(params.q, withHighlighter: {
highlighter, index, sr
if (!sr.highlights) {
sr.highlights = []
}
try {
sr.highlights[index] = highlighter.fragments("content")[0..2].join(" ")
} catch (IndexOutOfBoundsException ex) {
sr.highlights[index] = highlighter.fragment("content")
}
})
def suggestion = searchableService.suggestQuery(params.q)
if (suggestion != params.q) {
searchResult.suggestedQuery = suggestion
}
