Solr的亮點錯誤與useFastVectorHighlighter？

當我使用solr與useFastVectorHighlighter = true，我得到了一些錯誤。Solr的亮點錯誤與useFastVectorHighlighter？

這裏是我的查詢日誌：

[user] webapp= path=/select params={mm=1&hl.tag.post=</b>&qf=firstName+nickName^5+lastName&hl.tag.pre=<b>&wt=javabin&hl=true&version=2&rows=100&defType=dismax&hl.highlightMultiTerm=true&hl.useFastVectorHighlighter=true&start=0&q=a+bc&hl.boundaryScanner=breakIterator} hits=3767 status=500 QTime=266 ,someone can help me? but query with abc(without blank) is ok.

我固定BaseFragmentsBuilder（不得不檢查開始偏移比endOffset大），並在我們的項目Artifactory的創建修補JAR。排除原來的JAR與packagingExcludes並添加已修補的一個。我用了<version>標籤像3.6.1_patched分類會更容易Maven的。

好here is a link to my patched JAR.

主要是我做了一些偏差範圍檢查。 if語句修復了這個錯誤。

int startOffset = to.getStartOffset() - modifiedStartOffset[0] < 0 ? 0 : to.getStartOffset() - modifiedStartOffset[0]; 
int endOffset = to.getEndOffset() - modifiedStartOffset[0] > src.length()-1 ? src.length()-1 : to.getEndOffset() - modifiedStartOffset[0]; 
if (srcIndex < startOffset) { 
    fragment 
    .append(encoder.encodeText(src.substring(srcIndex, startOffset))) 
    .append(getPreTag(preTags, subInfo.getSeqnum())) 
    .append(encoder.encodeText(src.substring(startOffset, endOffset))) 
    .append(getPostTag(postTags, subInfo.getSeqnum())); 
} 
srcIndex = endOffset;

希望這可以幫助您使用FastVectorHighlighter。 Cheers Marcel
