Hi guys, while setting up my elasticsearch I have encountered a problem setting up the default index and default search analyzer. I want these analyzers to be used for all indexed data (I am using Tire gem for Ruby on Rails), so I guess that all I have to do is configure the elasticsearch.yml correctly. This is what I have so far: index: analysis: analyzer: default\_index: type: custom tokenizer: whitespace filter: [word\_delimiter, standard, lowercase, synonym, edgeNGram] default\_search: type: custom tokenizer: whitespace filter: [word\_delimiter, standard, lowercase, synonym] However, this analyzer does not seem to be applied while using the search in my application. All other settings are set to default. Any suggestions/corrections will be much appreciated. Thanks in advance. PN -- ---

Where are synonym and edgeNGram filters defined? Do you see any errors in the log file when you start elasticsearch? Did you reindex all records after changing the analyzer? Did you try using \_analyze command to see if your analyzer is having effect? On Wednesday, January 9, 2013 12:47:45 PM UTC-5, Patrick Norwood wrote: > no hints? -- ---

1. I was thinking that perhaps default settings would be applied so I did not define those filters, anyway, I left out synonym filter (don't need it for now) and the actual elasticsearch.yml looks like this: index : analysis : analyzer : default\_index : type : custom tokenizer : whitespace filter : [word\_delimiter, standard, lowercase, edgeNGram] default\_search : type : custom tokenizer : whitespace filter : [word\_delimiter, standard, lowercase] filter : edgeNGram : type : edgeNGram min\_gram : 2 max\_gram : 15 side : front 1. I don't see any errors after starting elasticsearch in the log file or console (running it with -f). 2. I don't know whether I am doing reindexing right, I simply delete indexes, restart the server, and create indexes again using rails console and som Tire commands. 3. I was playing with analyze API for quite some time, but I don't seem to get the right results, it seems that my analyzer does not have effect, or is not being loaded or I just don't know how to us analyze API :). Basically I tried it this way: Probably wrong approach, because analyzer default\_search or default\_index were not found (might this indicate they are not being loaded from .yml??): curl -XGET 'localhost:9200/\_analyze?analyzer=default\_search' -d 'testing string' curl -XGET 'localhost:9200/\_analyze?analyzer=default\_index' -d 'testing string' Then I tried it like this, and it seemed to have used the standard analyzer. curl -XGET 'localhost:9200/\_analyze?analyzer=default' -d 'testing string' I really don't know what I might be possibly doing wrong :).

1. This is strange because the mapping in 1. is wrong (filter: has wrong indentation, it has to be on the same level as analyzer), if you are editing correct config file, elasticsearch should fail to start. 2. That should be fine 3. As Clinton mentioned on IRC channel you need to specify an index. On Wednesday, January 9, 2013 2:36:38 PM UTC-5, Patrick Norwood wrote: > 1.

Thanks a lot Igor, your feedback helped me solve this issue. The main problem was indentation, how embarrassing :). -- ---
