屬性名稱

描述

Indexed

Indexed Field 可以進行搜索和排序。你還可以在 indexed Field 上運行 Solr 分析過程，此過程可修改內容以改進或更改結果。

Stored

stored Field 內容保存在索引中。這對于檢索和醒目顯示內容很有用，但對于實際搜索則不是必需的。例如，很多應用程序存儲指向內容位置的指針而不是存儲實際的文件內容。

<fieldType name="string" class="solr.StrField" sortMissingLast="true"/>

<fieldType name="boolean" class="solr.BoolField" sortMissingLast="true"/>

<fieldType name="int" class="solr.TrieIntField" precisionStep="0" positionIncrementGap="0"/>

<fieldType name="text_general" class="solr.TextField" positionIncrementGap="100">

<analyzer type="index">

? <tokenizer class="solr.StandardTokenizerFactory"/>

? <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt" enablePositionIncrements="true" />

? <filter class="solr.LowerCaseFilterFactory"/>

</analyzer>

<analyzer type="query">

? <tokenizer class="solr.StandardTokenizerFactory"/>

? <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt" enablePositionIncrements="true" />

? <filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt" ignoreCase="true" expand="true"/>

? <filter class="solr.LowerCaseFilterFactory"/>

</analyzer>

</fieldType>

屬性

描述

name

標識而已

class

和其他屬性決定了這個fieldType的實際行為。

sortMissingLast

設置成true沒有該field的數據排在有該field的數據之后，而不管請求時的排序規則, 默認是設置成false。

sortMissingFirst

跟上面倒過來唄。 默認是設置成false

analyzer

字段類型指定的分詞器

type

當前分詞用用于的操作.index代表生成索引時使用的分詞器query代碼在查詢時使用的分詞器

tokenizer

分詞器類

filter

分詞后應用的過濾器? 過濾器調用順序和配置相同.

<field name="id" type="string" indexed="true" stored="true" required="true" multiValued="false"/>

<field name="path" type="text_smartcn" indexed="false" stored="true" multiValued="false" termVector="true" />

<field name="content" type="text_smartcn" indexed="false" stored="true" multiValued="false" termVector="true"/>

<field name ="text" type ="text_ik" indexed ="true" stored ="false" multiValued ="true"/>

<field name ="pinyin" type ="text_pinyin" indexed ="true" stored ="false" multiValued ="false"/>

<field name="_version_" type="long" indexed="true" stored="true"/>

<dynamicField name="*_i" type="int" indexed="true" stored="true"/>

<dynamicField name="*_l" type="long" indexed="true" stored="true"/>

<dynamicField name="*_s" type="string" indexed="true" stored="true" />

<copyField source="content" dest="pinyin"/>

<copyField source="content" dest="text"/>

<copyField source="pinyin" dest="text"/>

屬性

描述

name

字段類型名

class

java類名

indexed

缺省true。 說明這個數據應被搜索和排序，如果數據沒有indexed，則stored應是true。

stored

缺省true。說明這個字段被包含在搜索結果中是合適的。如果數據沒有stored,則indexed應是true。

omitNorms

字段的長度不影響得分和在索引時不做boost時，設置它為true。

一般文本字段不設置為true。

termVectors

如果字段被用來做more like this 和highlight的特性時應設置為true。

compressed

字段是壓縮的。這可能導致索引和搜索變慢，但會減少存儲空間，只有StrField和TextField是可以壓縮，這通常適合字段的長度超過200個字符。

multiValued

字段多于一個值的時候，可設置為true。

positionIncrementGap

和multiValued一起使用，設置多個值之間的虛擬空白的數量

屬性

描述

useCompoundFile

通過將很多 Lucene 內部文件整合到一個文件來減少使用中的文件的數量。這可有助于減少 Solr 使用的文件句柄數目，代價是降低了性能。除非是應用程序用完了文件句柄，否則 false 的默認值應該就已經足夠。

ramBufferSizeMB

在添加或刪除文檔時，為了減少頻繁的更些索引,Solr會選緩存在內存中,當內存中的文件大于設置的值,才會更新到索引庫。較大的值可使索引時間變快但會犧牲較多的內存。如兩個值同時設置,滿足一個就會進行刷新索引.

maxBufferedDocs

mergeFactor

決定低水平的 Lucene 段被合并的頻率。較小的值（最小為 2）使用的內存較少但導致的索引時間也更慢。較大的值可使索引時間變快但會犧牲較多的內存。

maxIndexingThreads

indexWriter生成索引時使用的最大線程數

unlockOnStartup

unlockOnStartup 告知 Solr 忽略在多線程環境中用來保護索引的鎖定機制。在某些情況下，索引可能會由于不正確的關機或其他錯誤而一直處于鎖定，這就妨礙了添加和更新。將其設置為 true 可以禁用啟動鎖定，進而允許進行添加和更新。

lockType

single: 在只讀索引或是沒有其它進程修改索引時使用.

native: 使用操作系統本地文件鎖,不能使用多個Solr在同一個JVM中共享一個索引.

simple :使用一個文本文件鎖定索引.

屬性

描述

maxBooleanClauses

最大的BooleanQuery數量. 當值超出時，拋出 TooManyClausesException.注意這個是全局的,如果是多個SolrCore都會使用一個值,每個Core里設置不一樣的化,會使用最后一個的.

filterCache

filterCache存儲了無序的lucene document id集合，1.存儲了filter queries(“fq”參數)得到的document id集合結果。2還可用于facet查詢3. 3）如果配置了useFilterForSortedQuery，那么如果查詢有filter，則使用filterCache。

queryResultCache

緩存搜索結果,一個文檔ID列表

documentCache

緩存Lucene的Document對象,不會自熱

fieldValueCache

字段緩存使用文檔ID進行快速訪問。默認情況下創建fieldValueCache即使這里沒有配置。

enableLazyFieldLoading

若應用程序預期只會檢索 Document 上少數幾個 Field，那么可以將屬性設置為 true。延遲加載的一個常見場景大都發生在應用程序返回和顯示一系列搜索結果的時候，用戶常常會單擊其中的一個來查看存儲在此索引中的原始文檔。初始的顯示常常只需要顯示很短的一段信息。若考慮到檢索大型 Document 的代價，除非必需，否則就應該避免加載整個文檔。

queryResultWindowSize

一次查詢中存儲最多的doc的id數目.

queryResultMaxDocsCached

查詢結果doc的最大緩存數量, 例如要求每頁顯示10條,這里設置是20條,也就是說緩存里總會給你多出10條的數據.讓你點示下一頁時很快拿到數據.

listener

選項定義 newSearcher 和 firstSearcher 事件，您可以使用這些事件來指定實例化新搜索程序或第一個搜索程序時應該執行哪些查詢。如果應用程序期望請求某些特定的查詢，那么在創建新搜索程序或第一個搜索程序時就應該反注釋這些部分并執行適當的查詢。

useColdSearcher

是否使用冷搜索,為false時使用自熱后的searcher

maxWarmingSearchers

最大自熱searcher數量

名稱

描述

q

查詢字符串，必須的。

fq

filter query。使用Filter Query可以充分利用Filter Query Cache，提高檢索性能。作用：在q查詢符合結果中同時是fq查詢符合的，例如：q=mm&fq=date_time:[20081001 TO 20091031]，找關鍵字mm，并且date_time是20081001到20091031之間的。

fl

field list。指定返回結果字段。以空格“ ”或逗號“,”分隔。

start

用于分頁定義結果起始記錄數，默認為0。

rows

用于分頁定義結果每頁返回記錄數，默認為10。

sort

排序，格式:sort=<field name>+<desc|asc>[,<field name>+<desc|asc>]… 。示例：（inStock desc, price asc）表示先 “inStock” 降序, 再 “price” 升序，默認是相關性降序。

df

默認的查詢字段，一般默認指定。

q.op

覆蓋schema.xml的defaultOperator（有空格時用"AND"還是用"OR"操作邏輯），一般默認指定。必須大寫

wt

writer type。指定查詢輸出結構格式，默認為“xml”。在solrconfig.xml中定義了查詢輸出格式：xml、json、python、ruby、php、phps、custom。

qt

query type，指定查詢使用的Query Handler，默認為“standard”。

explainOther

設置當debugQuery=true時，顯示其他的查詢說明。

defType

設置查詢解析器名稱。

timeAllowed

設置查詢超時時間。

omitHeader

設置是否忽略查詢結果返回頭信息，默認為“false”。

indent

返回的結果是否縮進，默認關閉，用 indent=true|on 開啟，一般調試json,php,phps,ruby輸出才有必要用這個參數。

version

查詢語法的版本，建議不使用它，由服務器指定默認值。

debugQuery

設置返回結果是否顯示Debug信息。

SolrQuery query = new SolrQuery();

query.set("q","*.*");

query.setHighlight(true); // 開啟高亮組件

query.addHighlightField("content");// 高亮字段

query.setHighlightSimplePre(PRE_TAG);// 標記

query.setHighlightSimplePost(POST_TAG);

QueryResponse rsp =server.query(query)

//…上面取結果的代碼

//取出高亮結果

if (rsp.getHighlighting() != null) {

? if (rsp.getHighlighting().get(id) != null) {//先通過結果中的ID到高亮集合中取出文檔高亮信息

??? Map<String, List<String>> map = rsp.getHighlighting().get(id);//取出高亮片段

??? if (map.get(name) != null) {

????? for (String s : map.get(name)) {

??????? System.out.println(s);

????? }

??? }
