Method withSearcher

solr/core/src/java/org/apache/solr/core/SolrCore.java:2151–2159

Executes the lambda with the SolrIndexSearcher. This is more convenient than using #getSearcher() since there is no ref-counting business to worry about. Example: IndexReader reader = h.getCore().withSearcher(SolrIndexSearcher::getIndexReader); Wa

(IOFunction<SolrIndexSearcher, R> lambda)

    return getSearcher(false, true, null);
  }

   * Executes the lambda with the {@link SolrIndexSearcher}. This is more convenient than using

   *
   * <pre class="prettyprint">

   *
   * Warning: although a lambda is concise, it may be inappropriate to simply return the IndexReader
   * because it might be closed soon after this method returns; it really depends.
