Unfortunately there is no general support for this feature. But you can approximate it if you have a relatively small set of compound terms using the DictionaryCompoundWordTokenFilterFactory: http://lucene.apache.org/core/5_4_0/analyzers-common/org/apache/lucene/analysis/compound/DictionaryCompoundWordTokenFilterFactory.html
The doc is weak. I do have some examples in my old Solr 4.x Deep Dive e-book: http://www.lulu.com/shop/jack-krupansky/solr-4x-deep-dive-early-access-release-7/ebook/product-21203548.html You might also be able to achieve a similar effect with synonyms, but again only if the set of terms is reasonably small. -- Jack Krupansky On Thu, Dec 17, 2015 at 1:45 PM, Xiaolong Zheng <zhengxiaol...@gmail.com> wrote: > Hi All, > > I want to know what's the common way to implement the searching with > whitespace removal.
