问题 I am currently searching my database with a query (using JDBC) like this: "... AND LCASE(Items.Name) LIKE '%" + searchString.toLowerCase() + "%';" Now, this is obviously very bad, because it allows for SQL injection as well as insertion of wildcard symbols such as % and _.

问题 I'm evaluating Magento for a travel company who will need to do product searches and recommendations based on geographical distance. The company is creating custom holiday packages based on various components (eg: accommodation, tours, restaurant vouchers, etc).

问题 I am trying to setup a search engine using Solr (or Lucene) which could have text in both Latin with special chars, (special chars would include Ö or Ç as an example) or Cyrilic chars (examples include Б or б and Ж ж).
