Peter Barna commented on LUCENE-6807: ------------------------------------- Errors appear to be an API change sometime in the intervening 5 years. Appears to be a simple swap to {{PointsConfig}}, {{PointQueryNode}}, and {{PointRangeQueryNode}} from the {{Numeric*}} equivalents. > AbstractRangeQueryNode toQueryString not working as intended > ------------------------------------------------------------ > > Key: LUCENE-6807 > URL: https://issues.apache.org/jira/browse/LUCENE-6807 > Project: Lucene - Core > Issue Type: Bug > Components: core/queryparser > Affects Versions: 5.3 > Reporter: Peter Barna > Priority: Minor > Attachments: LUCENE-6807-option1.patch, LUCENE-6807-option1.patch, > LUCENE-6807-option2.patch, LUCENE-6807-option3.patch > > Original Estimate: 48h > Remaining Estimate: 48h > > It is my understanding that for a given {{QueryNode}} node, > {{parse(node.toQueryString());}} should return a {{QueryNode}} which is > functionally identical to the original node. > That is not the case with AbstractQueryNode: > if we have a range query on FIELD from "A" to "B" ({{node = parse("FIELD:[A > B]")}}), then {{node.toQueryString()}} will return "[FIELD:A FIELD:B]" which, > in turn, is parsed as a range query on the default field from "FIELD:A" to > "FIELD:B". > As far as I know, this affects all versions of lucene. > I believe I have the knowledge to provide the patch, so I will be working on > that today. > As of now, I have thought of two options to implement this fix, both of which > involve modifying the {{ValueQueryNode}} interface to include a method which > returns {{value}} as a {{CharSequence}}. > The first option is to add a new method to the interface which returns > (formatted if necessary) the value as a {{CharSequence}} and implement it in > all implementing classes ({{FieldQueryNode}} and {{NumericQueryNode}}). Then > in {{AbstractQueryNode#toQueryString()}} we will call that method and escape > the values using the provided {{EscapeQuerySyntax}}. > The second option is to make the protected method {{getTermEscaped()}}, which > is already present in all implementing classes, public, and add it to the > interface. > While I think that the second option is certainly cleaner, I do not know why > this method is protected in the first place, so I will proceed with the first > option until someone who is more familiar with the lucene project than I am > can comment on the matter. > As I am writing this, it occurs to me that implementing the first option is > essentially just bypassing the protected scope on {{getTermEscapeed()}}, so > maybe it is correct to just review whether or not that method needs to be > protected. It also occurred to me to use the existing {{getValue()}} method, > and format and escape the {{toString()}} of that, but that depends on a > generic class having implemented {{toString()}} in a way that plays nicely > with the query parser, so, to me, this is below the two previously mentioned > options. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@lucene.apache.org For additional commands, e-mail: issues-h...@lucene.apache.org
