如查詢的條件爲:params.add("fq", "jiucaiyun_brand:Double A" ),這樣是查不出帶有空格的條件,須要把空格轉義app
if(brand2.contains(" ")) {
brand2=brand2.replace(" " , "\\ ");
}
params.add("fq", "jiucaiyun_brand:" + brand2);這樣就能夠查出匹配的結果。.net
其餘字符處理:+ – && || ! ( ) { } [ ] ^ 」 ~ * ? : \和空格orm
public static String transformSolrMetacharactor(String input){
StringBuffer sb = new StringBuffer();
String regex = "[+\\-&|!(){}\\[\\]^\"~*?:(\\)\\s]";
Pattern pattern = Pattern.compile(regex);
Matcher matcher = pattern.matcher(input);
while(matcher.find()){
matcher.appendReplacement(sb, "\\\\"+matcher.group());
}
matcher.appendTail(sb);
return sb.toString();
}
