Hi all, I've been using elasticsearch-1.2.1 and I've been indexing .xml and .jsp file content. And this is how my index has been analyzed as: ``` "settings": { "analysis": { "filter": { "word_delimiter" : { "type" : "word_delimiter", "preserve_original" : true, "split_on_case_change" : false, "stem_english_possessive" : false, "type_table" : [ "# => ALPHA", "@ => ALPHA", "$ => ALPHA", "& => ALPHA", "? => ALPHA", "= => ALPHA" ] } }, "analyzer": { "custom_analyzer" : { "type" : "custom", "tokenizer" : "whitespace", "filter" : ["word_delimiter", "lowercase"] } } } ``` And the file contains one of the lines as, _\<%@ page import="java.util.Vector" %\>_. While searching the index as _import="java.\*\*, i'm getting the result as expected. But while searching for the keyword_ "import"\*, I dint get any of the result. On analyzing with the help of kopf plugin, I came to know my content \*import="java.util.Vector" \*was indexed into \*import="java.util.Vector", \*\*import=, \*_java, util and vector._ But what I want is \*import= _to be indexed as it is and as well as_ import, \*so that it'll match my scenario. Also I've tried other option i.e. without the type\_table, in that case my search results gets reversed. The keyword search for _"import"_ works and _import="java._" \*doesn't seems to be working. Anybody have any idea on how the index should be analyzed to get my desired index? -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

In the type\_table mentioned above, assinging "= =\> DIGIT" instead of "= =\>ALPHA" yields the indexing as I expected.
