POFilename search with ElasticSearch
text
Body
copied!<p>I want to use ElasticSearch to search filenames (not the file's content). Therefore I need to find a part of the filename (exact match, no fuzzy search).</p> <p>Example:<br> I have files with the following names:</p> <pre><code>My_first_file_created_at_2012.01.13.doc My_second_file_created_at_2012.01.13.pdf Another file.txt And_again_another_file.docx foo.bar.txt </code></pre> <p>Now I want to search for <code>2012.01.13</code> to get the first two files.<br> A search for <code>file</code> or <code>ile</code> should return all filenames except the last one.</p> <p>How can i accomplish that with ElasticSearch?</p> <p>This is what I have tested, but it always returns zero results:</p> <pre><code>curl -X DELETE localhost:9200/files curl -X PUT localhost:9200/files -d ' { "settings" : { "index" : { "analysis" : { "analyzer" : { "filename_analyzer" : { "type" : "custom", "tokenizer" : "lowercase", "filter" : ["filename_stop", "filename_ngram"] } }, "filter" : { "filename_stop" : { "type" : "stop", "stopwords" : ["doc", "pdf", "docx"] }, "filename_ngram" : { "type" : "nGram", "min_gram" : 3, "max_gram" : 255 } } } } }, "mappings": { "files": { "properties": { "filename": { "type": "string", "analyzer": "filename_analyzer" } } } } } ' curl -X POST "http://localhost:9200/files/file" -d '{ "filename" : "My_first_file_created_at_2012.01.13.doc" }' curl -X POST "http://localhost:9200/files/file" -d '{ "filename" : "My_second_file_created_at_2012.01.13.pdf" }' curl -X POST "http://localhost:9200/files/file" -d '{ "filename" : "Another file.txt" }' curl -X POST "http://localhost:9200/files/file" -d '{ "filename" : "And_again_another_file.docx" }' curl -X POST "http://localhost:9200/files/file" -d '{ "filename" : "foo.bar.txt" }' curl -X POST "http://localhost:9200/files/_refresh" FILES=' http://localhost:9200/files/_search?q=filename:2012.01.13 ' for file in ${FILES} do echo; echo; echo ">>> ${file}" curl "${file}&pretty=true" done </code></pre>
