It supports the most common highlighting parameters and can handle just about any query accurately, even SpanQueries (e.g. as seen from the <code>surround</code> parser). A strong benefit to this highlighter is that you can opt to configure Solr to put more information in the underlying index to speed up highlighting of large documents; multiple configurations are supported, even on a per-field basis.

Its ability to highlight just about any query accurately is a strength shared with the Unified Highlighter (they share some code for this in fact). The Original Highlighter will normally analyze stored text on the fly in order to highlight. It will use full term vectors if available, however in this mode it isn’t as fast as the Unified Highlighter or FastVector Highlighter. This highlighter is a good choice for a wide variety of search use-cases. Where it falls short is performance; it’s often twice as slow as the Unified Highlighter.

all the others do), which could pose a challenge for some languages.</p>
