how to use IgnoreAllNoiseQuery property and EnableStemming corretly?

Question

When using search query services to get search result, if I query the keyword like "a", "the", the services will throw an exceptions, says they are common words.
But Seems I change the IgnoreAllNoiseQuery property (whatever false or true) in query xml, it's not useful, the exception still be thrown.

Anyone can help to explain this?

Other problem is: when I query keywords like "Build", the result will return different terms like "Build", "Built", but only "Build" is highlighted. How can we make other terms of the word to be highlighted?

Thanks.

Its by design property set by SharePoint. you can try changing it by editing query XML file as follows:

<SearchTemplates>
  <QueryPacketTemplate>
    <QueryPacket xmlns="urn:Microsoft.Search.Query">
      <Query>
        <SupportedFormats>
          <Format>urn:Microsoft.Search.Response.Document.Document</Format>
        </SupportedFormats>
        <Context>
          <QueryText type="STRING" language="en-us">searchkeyword</QueryText>
        </Context>
        <Range>
          <StartAt>1</StartAt>
          <Count>10</Count>
        </Range>
        <Properties>
          <Property name="Title"/>
          <Property name="Path"/>
          <Property name="Description"/>
          <Property name="Write"/>
          <Property name="Rank"/>
          <Property name="Size"/>
          <Property name="Author"/>
          <Property name="HitHighlightedSummary"/>
        </Properties>
        <EnableStemming>true</EnableStemming>
        <TrimDuplicates>true</TrimDuplicates>
        <IgnoreAllNoiseQuery>true</IgnoreAllNoiseQuery>
        <ImplicitAndBehavior>true</ImplicitAndBehavior>
        <IncludeRelevanceResults>true</IncludeRelevanceResults>
        <IncludeSpecialTermResults>true</IncludeSpecialTermResults>
        <IncludeHighConfidenceResults>true</IncludeHighConfidenceResults>
      </Query>
    </QueryPacket>
  </QueryPacketTemplate>
</SearchTemplates>

Thank you Yogesh. But I don't think it will work.

For the first one, should I empty the noise word list if I want to query noise words?

For the second one, is it designed by default?

Hi Allen,

You can empty the noise word list and then restart Osearch and perform full crawl again and then you will be able to query those noise words. For more information, you can follow below technet article:
