问题描述
我有一种情况，我使用Cassandra的数据库，我需要全文搜索功能。
现在我知道Apache Solr，Apache Cassandra和DSE搜索。
但是，我不想使用昂贵的专有软件搜索）。我不想使用Apache Solr的原因是因为我不想处理HA，分片和冗余。 Cassandra是完美的HA，分片和冗余;我想在现有的Cassandra DB中存储我的全文索引。
所以我要找的是将一个字符串分解为可索引部分。例如：
字符串input =我喜欢苹果和bannanas;
String tokens [] = makeTokenIndex（input）;pre>
// tokens = {I，like，apples，bannanas，apple，bannana}
显然我可以在空格上分割字符串，并使用单词作为索引键。但我正在寻找比这更聪明的东西。可以处理复数，找到单词的根等等...
修改Apache Lucene是最好的解决方案，还是有另一个选项？ / p>
解决方案我没有使用Cassandra，但我想你说的是使用一个Cassandra实现Lucene的界面。 Lucene使用目录与存储机制交互。
我发现了几个可能有帮助的项目：
我不能说出任何一个的经验。
I've got a situation where I'm using Cassandra for DB and I need full-text search capability. Now I'm aware of Apache Solr, Apache Cassandra, and DSE search.
However, I do not want to use a costly and proprietary software(DSE search). The reason I do not want to use Apache Solr is because I don't want to deal with HA, sharding, and redundency for it. Cassandra is perfect for HA, sharding, and redundency; I would like to store my full-text index in the existing Cassandra DB.
So what I'm looking for is something that will break down a string into its indexable parts. For example:
String input = "I like apples and bannanas.";
String tokens[] = makeTokenIndex(input);
//tokens = {"I","like","apples","bannanas","apple","bannana"}
Obviously I could split strings on spaces and use the words as index-keys. But I'm looking for something smarter than that. Something that can handle plurals, find the root of a word, etc...
Would modifying Apache Lucene be the best solution for this, or is there another option?
I've not used Cassandra, but I think you're talking about using a Cassandra implementation of Lucene's Directory interface. Lucene uses a Directory to interact with a storage mechanism.
I found a couple of projects that might help:
I can't speak with experience about either one, though.
