我正在使用Solr 3.6.2来提取我确定包含特定字符串的文档的片段。 （首先，这种用法是否正确？）不幸的是，我得到的片段不包含我的查询字符串（简单，单一，不停的字）。
例如，对于我知道包含“funmitflags”的文档123456，我有一个类型的查询：
id:123456 and content_en:funmitflags
和
fl=id&hl=true&hl.fl=content_en&hl.snippets=2&hl.alternateField=content_en&hl.maxAlternateFieldLength=400&hl.maxAnalyzedCharacters=2147483647&hl.fragsize=400&rows=100
（我将“content_en”作为备用字段，以便从文档中获取任何代码段。 我通常在这个领域有大量的文本。） 但是，现在我通常会返回前400个字符而不是那些包含我的“funmitflags”字样的字符。
无论如何，我可以从管理页面检索文档，而不是正确的高亮显示。 这很尴尬，因为大约75％的查询都存在这个问题。
在我的schema.xml中，我将“content_en”定义为“text_en”。
<field name="content_en" type="text_en" indexed="true" stored="true" />
我将“text_en”从原始定义更改为以下内容：
<fieldType name="text_en" class="solr.TextField" positionIncrementGap="100">
<analyzer type="index">
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<filter class="solr.StopFilterFactory"
ignoreCase="true"

<filter class="solr.EnglishPossessiveFilterFactory"/>
<filter class="solr.KeywordMarkerFilterFactory" protected="protwords.txt"/>
<filter class="solr.PorterStemFilterFactory"/>

</fieldType>
重新编制索引，我在这两种情况下都没有得到正确的摘录。 有人能指点我吗？ 我是否应始终获得包含搜索字的片段？
答案 0 :(得分：1)
只是尝试在使用您的分析器链的largetext_en类型的字段text_en上突出显示。突出显示工作正常，4个片段包含搜索的单词Polyana，如下所示。 （很难阅读下面字段的内容，因此请将粘贴复制到文本编辑器中并查看。）

"COUNT LEO NIKOLAYEVICH TOLSTOY was born August 28, 1828, at the family estate of Yasna- ya Polyana, in the province of Tula. His moth- er died when he was three and his father six years later. Placed in the care of his aunts, he passed many of his early years at Kazan, where, in 1844, after a preliminary training by French tutors, he entered the university. He cared lit- tle for the university and in 1847 withdrew be- cause of "ill-health and domestic circum- stances." He had, however, done a great deal of reading, of French, English, and Russian novels, the New Testament, Voltaire, and Hegel. The author exercising the greatest in- fluence upon him at this time was Rousseau; he read his complete works and for sometime wore about his neck a medallion of Rousseau. Immediately upon leaving the university, Tolstoy returned to his estate and, perhaps inr spired by his enthusiasm for Rousseau, pre- pared to devote himself to agriculture and to improving the condition of his serfs. His first attempt at social reform proved disappointing, and after six months he withdrew to Moscow and St. Petersburg, where he gave himself over to the irregular life characteristic of his class and time. In 1851, determined to "escape my debts and, more than anything else, my hab- its," he enlisted in the Army as a gentleman- volunteer, and went to the Caucasus. While at Tiflis, preparing for his examinations as a cadet, he wrote the first portion of the trilogy, Childhood, Boyhood, and Youth, in which he celebrated the happiness of "being with Na- ture, seeing her, communing with her." He al- so began The Cossacks with the intention of showing that culture is the enemy of happi- ness. Although continuing his army life, he gradually came to realize that "a military ca- reer is not for me, and the sooner I get out of it and devote myself entirely to literature the better." His Sevastopol Sketches (1855) were so successful that Czar Nicholas issued special orders that he should be removed from a post of danger. Returning to St. Petersburg, Tolstoy was re- ceived with great favor in both the official and literary circles of the capital. He soon became interested in the popular progressive move- ment of the time, and in 1857 he decided to go abroad and study the educational and munici- pal systems of other countries. That year, and again in 1860, he traveled in Europe. At Yas- naya Polyana in 1861 he liberated his serfs and opened a school, established on the principle that "everything which savours of compulsion is harmful." He started a magazine to promote his notions on education and at the same time served as an official arbitrator for grievances between the nobles and the recently emanci- pated serfs. By the end of 1863 he was so ex- hausted that he discontinued his activities and retired to the steppes to drink koumis for his health. Tolstoy had been contemplating marriage for some time, and in 1862 he married Sophie Behrs, sixteen years his junior, and the daugh- ter of a fashionable Moscow doctor. Their early married life at Yasnaya Polyana was tranquil. Family cares occupied the Countess, and in the course of her life she bore thirteen children, nine of whom survived infancy. Yet she also acted as a copyist for her husband, who after their marriage turned again to writ- ing. He was soon at work upon "a novel of the i8io's and *2o's" which absorbed all his time and effort. He went frequently to Mos- cow, "studying letters, diaries, and traditions" and "accumulated a whole library" of histori- cal material on the period. He interviewed survivors of the battles of that time and trav- eled to Borodino to draw up a map of the battleground. Finally, in 1869, after his work had undergone several changes in conception and he had "spent five years of uninterrupted andjgxceptionally strenuous labor Tnnierthe IbesfcondUtions of life/' he published War and Peace. Its appearance immediately established Tolstoy's reputation, and in the judgment of Turgenev, the acknowledged dean of Russian letters, gave him "first place among all our contemporary writers." The years immediately following the com- pletion of War and Peace were pa**efl in a great variety of occupations, none of which Tohtoy found satisfying. He tried busying VI BIOGRAPHICAL NOTE himself with the affairs of his estate, under- took the learning of Greek to read the ancient classics, turned again to education, wrote a series of elementary school books, and served as school inspector. With much urging from his wife and friends, he completed Anna Kare- nina, which appeared serially between 1875 and 1877. Disturbed by what he considered his unreflective and prosperous existence, Tolstoy became increasingly interested in religion. At first he turned to the orthodox faith of the people. Unable to find rest there, he began a detailed examination of religions, and out of his reading, particularly of the Gospels, gradu- ally evolved his own personal doctrine. Following his conversion, Tolstoy adopted a new mode of life. He dressed like a peasant, devoted much of his time to manual work, learned shoemaking, and followed a vegetari- an diet. With the exception of his youngest daughter, Alexandra, Tolstoy's family re- mained hostile to his teaching. The breach be- tween him and his wife grew steadily wider. In 1879 he wrote the Kreutzer Sonata in which he attacked the normal state of marriage and extolled a life of celibacy and chastity. In 1881 he divided his estate among his heirs and, a few years later, despite the opposition of his wife, announced that he would forego royal- ties on all the works published after his con- version. Tolstoy made no attempt at first to propa- gate his religious teaching, although it attracted many followers. After a visit to the Moscow slums iri 1881, he became concerned with social conditions, and he subsequently aided the suf- ferers of the famine by sponsoring two hun- dred and fifty relief kitchens. After his meet- ing and intimacy with Chertkov, "Tolstoyism" began to develop as an organized sect. Tol- stoy's writings became almost exclusively pre- occupied with religious problems. In addition to numerous pamphlets and plays, he wrote IV hat is Art? (1896), in which he explained his new aesthetic theories, and Hadji-Murad, (1904), which became the favorite work of his old age. Although his activities were looked upon with increasing suspicion by the official authorities, Tolstoy escaped official censure until 1901, when he was excommunicated by the Orthodox Church. His followers were f re- quently subjected to persecution, and many were either banished or imprisoned. Tolstoy's last years were embittered by mounting hostility within his own household. Although his personal life was ascetic, he felt the ambiguity of his position as a preacher of poverty living on his great estate. Finally, at the age of eighty-two, with the aid of his daugh- ter, Alexandra, he fled from home. His health broke down a few days later, and he was re- moved from the train to the station-master's hut at Astopovo, where he died, November 7, 1910. He was buried at Yasnaya Polyana, in the first public funeral to be held in Russia without religious rites. "

感谢@ arun的实验截断了一半的可能性，我找到了解决方案。
由于我的文字很大，我在solrconfig.xml中设置
<maxFieldLength>1000000</maxFieldLength>
为了提高速度，我开始使用fastVectorHighlighter：
solrQuery.set("hl.useFastVectorHighlighter", true);
我的查询。似乎它禁用了我的highligherSimplePre和highligherSimplePost，但谁在乎。
另外，我必须在我的内容字段中添加术语*选项：
` <field name="content_en" type="text_en" indexed="true" stored="true" termVectors="true" termPositions="true" termOffsets="true" />`

请注意，该查询包含hl.maxAnalyzedCharacters=2147483647，但这是错误的参数名称 - 而不是hl.maxAnalyzedChars
