Aaron McCurry commented on BLUR-44:
-----------------------------------
Good questions.
Basically, the default types in Blur (Text, String, Int, Long, Float, Double,
and Binary) all have default behaviors.
Text - Will use the BlurAnalyzer and the default analyzer is the
StandardAnalyzer.
String - Is not Analyzed and is indexed as the a single token the normal
StringField in Lucene.
Int - Is not Analyzed and is indexed as an integer the normal IntegerField in
Lucene.
Long - Is not Analyzed and is indexed as an long the normal LongField in Lucene.
Float - Is not Analyzed and is indexed as an float the normal FloatField in
Lucene.
Double - Is not Analyzed and is indexed as an double the normal DoubleField in
Lucene.
Binary - by default is not indexed, but just stored.
Also take a look at the Blur.Thrift file. I have tried to describe the
behavior as much as possible.
The BlurAnalyzer should work in conjunction with any classes that are defined
in the ClassDefinition (Thrift) that extend o.a.b.a.IndexableFieldFactory to
allow for none default behaviors.
Example 1:
User simply wants to use the ClassicAnalyzer instead of the StandardAnalyzer
for a Text field. Then the class name for ClassicAnalyzer should be defined in
the ClassDefinition.
Analyzer {
analyzerTypes [
AnalyzerType {
fieldName:SomeUserFieldName,
classDefinition:o.a.l.a.ClassicAnalyzer
}
]
}
Example 2:
User has a custom indexing strategy that requires a custom implemented
IndexableField (Lucene Type). The instead of providing a lucene analyzer in
the ClassDefinition they provide a o.a.b.a.IndexableFieldFactory class. This
will allow the user to convert the Thrift Field into the IndexableField.
Analyzer {
analyzerTypes [
AnalyzerType {
fieldName:SomeUserFieldName,
classDefinition:some.custom.class.CustomIndexableFieldFactory
}
]
}
> Update BlurAnalyzer to use the Blur Thrift Analyzer object.

> The BlurAnalyzer constructor that takes a
> org.apache.blur.thrift.generated.Analyzer currently does nothing. Obviously
> this needs to be implemented, I have added javadocs to the Blur thrift API
