golang全文搜索--使用sphinx

不多废话,测试环境 `ubuntu 13.10` ## 安装 sudo apt-get install sphinxsearch ## 配置 nano /etc/sphinxsearch/sphinx.conf # 数据源配置 source default { type = xmlpipe2 xmlpipe_command = /path/xmlpipe2 xmlpipe_fixup_utf8 = 1 } # 索引配置 index default { type = plain source = default # 索引文件路径 path = /path/filename # 不存储文档信息 docinfo = none #最小索引词长度 min_word_len = 2 charset_type = utf-8 # 指定utf-8的编码表 charset_table = 0..9, A..Z->a..z, _, a..z, U+410..U+42F->U+430..U+44F, U+430..U+44F # 简单分词,只支持0和1,如果要搜索中文,请指定为1 ngram_len = 1 # 需要分词的字符,如果要搜索中文,去掉前面的注释 ngram_chars = U+3000..U+2FA1F } ## xmlpipe2的格式 ... ... ... ... 只要配置文件中 xmlpipe_command 字段配置的可执行文件输出为相应的xml流即可,这样几乎适配了所有数据源 ## 生成索引 $ indexer default Sphinx 2.0.4-release (r3135) Copyright (c) 2001-2012, Andrew Aksyonoff Copyright (c) 2008-2012, Sphinx Technologies Inc (http://sphinxsearch.com) using config file '/etc/sphinxsearch/sphinx.conf'... indexing index 'default'...
