领先的通配符在Lucene.NET中引发错误 [英] Leading wildcard character throws error in Lucene.NET

问题描述

如果搜索查询中包含前导通配符(*或?)，则QueryParser的Parse函数将引发错误.

If the search query contains a leading wildcard character (* or ?), the QueryParser's Parse function throws an error.

Dim q As String = "*abc"
Dim qp As New QueryParser("text", New StandardAnalyzer())
Dim query As Query = qp.Parse(q)

在Lucene.NET v2.0.0.4中有什么方法可以解决此问题?

Is there any way to solve this problem in Lucene.NET v2.0.0.4?

推荐答案

设置

Set QueryParser.SetAllowLeadingWildcard Method to true. The API page states that "this can produce very slow queries on big indexes" though.
