128 | the conditions stated in this License.
129 |
130 | 5. Submission of Contributions. Unless You explicitly state otherwise,

133 | this License, without any additional terms or conditions.
134 | Notwithstanding the above, nothing herein shall supersede or modify
135 | the terms of any separate license agreement you may have executed
136 | with Licensor regarding such Contributions.
137 |
138 | 6. Trademarks. This License does not grant permission to use the trade
139 | names, trademarks, service marks, or product names of the Licensor,
140 | except as required for reasonable and customary use in describing the
141 | origin of the Work and reproducing the content of the NOTICE file.
142 |
143 | 7. Disclaimer of Warranty. Unless required by applicable law or
144 | agreed to in writing, Licensor provides the Work (and each
145 | Contributor provides its Contributions) on an "AS IS" BASIS,
146 | WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or

157 | liable to You for damages, including any direct, indirect, special,
158 | incidental, or consequential damages of any character arising as a
159 | result of this License or out of the use or inability to use the
160 | Work (including but not limited to damages for loss of goodwill,
161 | work stoppage, computer failure or malfunction, or any and all
162 | other commercial damages or losses), even if such Contributor
163 | has been advised of the possibility of such damages.
164 |
165 | 9. Accepting Warranty or Additional Liability. While redistributing
166 | the Work or Derivative Works thereof, You may choose to offer,
167 | and charge a fee for, acceptance of support, warranty, indemnity,
168 | or other liability obligations and/or rights consistent with this
169 | License. However, in accepting such obligations, You may act only
170 | on Your own behalf and on Your sole responsibility, not on behalf
171 | of any other Contributor, and only if You agree to indemnify,
172 | defend, and hold each Contributor harmless for any liability
173 | incurred by, or claims asserted against, such Contributor by reason
174 | of your accepting any such warranty or additional liability.

1 | Term List Matching Plugin for ElasticSearch
2 | ==================================
3 |
4 | Similar functionality to Lucene/Solr's TermsComponent.
5 | This Term List plugin will do simple matching against the complete term list found directly in Lucene.
6 |
7 | 1. Build this plugin:
8 |
9 | mvn clean compile test package
10 | # this will create a file here: target/releases/elasticsearch-term-plugin-1.0-SNAPSHOT.zip
11 | PLUGIN_PATH=`pwd`/target/releases/elasticsearch-term-plugin-1.0-SNAPSHOT.zip
12 |
13 | 2. Install the PLUGIN
14 |
15 | cd $ELASTICSEARCH_HOME
16 | ./bin/plugin -url file:/$PLUGIN_PATH -install elasticsearch-term-plugin
17 |
18 | 3. Updating the plugin
19 |
20 | cd $ELASTICSEARCH_HOME
21 | ./bin/plugin -remove elasticsearch-term-plugin
22 | ./bin/plugin -url file:/$PLUGIN_PATH -install elasticsearch-term-plugin
23 |
24 |
25 | Usage
26 | ==========
27 |
28 | ##### Version
29 |
30 | ElasticSearch version 0.90.6
31 |
32 | ##### Facet Parameters
33 | * fields - list of fields to examine for terms, this is the only required field
34 | * search - substring to search for (case insensitive)
35 | * max_per_shard - max number of terms to pull from a shard
36 | * prefix - (true/false) defaults to false, is the search to be used for prefix/starts with matching only?
37 | * sort - (true/false) default to true, should returned list by alpha sorted
38 | * case_insenstive - (true/false) defaults to true, should matching be done disregarding case
39 |
40 | ##### Facet example
41 |
42 | "facets" : {
43 | "term_list_facet" : {
44 | "term_list" : {
45 | "fields" : [ "company", "other.company" ],
46 | "search" : "alt",
47 | "prefix" : false,
48 | "sort" : true,
49 | "case_insenstive" : true,
50 | "max_per_shard" : 10
51 | }
52 | }
53 | }
54 |
55 | ##### Results Example
56 | ```
57 | ...
58 | "facets":{
59 | "term_list_facet":{
60 | "_type":"term_list",
61 | "entries":[
62 | "alternet magic inc.",
63 | "altech tech technology chickens",
64 | "system altibox corp",
65 | "baltiware tv station llc"
66 | ]
67 | }
68 | }
69 | ```
70 | ###### setup test index
71 | Note the analyzer configuration of tokenizer keyword, if you for example use the whitespace tokenizer your results will be strange
72 |
73 | curl -XDELETE localhost:9200/my_test_index
74 |
75 | curl -XPOST localhost:9200/my_test_index -d '{
76 | "settings" : {
77 | "analysis": {
78 | "analyzer": {
79 | "default": {
80 | "filter": "lowercase",
81 | "type": "custom",
82 | "tokenizer": "keyword"
83 | }
84 | }
85 | }
86 | }
87 | }'
88 |
89 | ###### place test data in index
90 |
91 | curl -XPUT localhost:9200/my_test_index/my_test_type/1 -d '{
92 | "my_test_type" : {
93 | "company" : "Walt Disney",
94 | "desc" : "A movie company and a TV channel",
95 | "other" : {"company" : "Walt Disney Theme Parks"}
96 | }
97 | }'
98 |
99 | curl -XPUT localhost:9200/my_test_index/my_test_type/2 -d '{
100 | "my_test_type" : {
101 | "company" : "Walts Plumbing",
102 | "desc" : "Best plumber in town",
103 | "other" : {"company" : "Walts waterproof rubber chicken company"}
104 | }
105 | }'
106 |
107 | ###### query data with custom facet
108 |
109 | curl -XGET localhost:9200/my_test_index/_search?pretty=1 -d '{
110 | "query" : {
111 | "match_all" : { }
112 | },
113 | "facets" : {
114 | "term_list_facet" : {
115 | "term_list" : {
116 | "fields" : [ "company", "other.company" ],
117 | "search" : "alt",
118 | "prefix" : false,
119 | "max_per_shard" : 10
120 | }
121 | }
122 | }
123 | }'
