| FIXME In the default settings, the concordance is ordered according to the order in which the search results (individual concordance lines) are found in the corpus (e.g. in the corpus [[en:cnk:syn2015|SYN2015]] the first texts are fiction, then non-fiction and finally journalistic). This has the advantage of making it quicker to find matching rows. Nonetheless, if the concordance is extensive, and one needs to acquire a representative sample (e.g. for manual analysis), it is preferable to work with randomly shuffled lines. This can be done with the **Concordance → Shuffle** option. The resulting shuffle of the concordance lines is random yet repeatable. | In the default settings, the concordance is ordered according to the order in which the search results (individual concordance lines) are found in the corpus (e.g. in the corpus [[en:cnk:syn2015|SYN2015]] the first texts are fiction, then non-fiction and finally journalistic).

| Using the Shuffle option automatically is recommended, as it ensures that every concordance, before being displayed, is randomized in this way. The permanent setting of concordance lines shuffling is achievable in the **View → General view options** menu (the /Shuffle concordance lines by default// option). Such an approach functions as an effective prevention against drawing incorrect conclusions from studying a sample of results which originate from an unrepresentative set of texts. | Using the Shuffle option automatically is recommended, as it ensures that every concordance, before being displayed, is randomized in this way.

| If concordance lines shuffling is enabled by default, the Shuffle option will perform another random rearrangement. For each concordance, an explicit shuffling algorithm causes the results after the first, second, third... nth shuffle to match on repeated attempts on the same query. This guarantees the repeatability of experiments on corpora even when using a shuffled concordance. | If concordance lines shuffling is enabled by default, the Shuffle option will perform another random rearrangement.
